Tundra 4wd conversion - Page 3

caligula455 · 07-01-2008, 05:26 AM

here is the connector i cut off the short ADD harness. i peeled the wires out of the loom and staggered the cuts so the splices weren't all in the same spot which makes the bundle really thick.

here is a picture of the extended ADD motor harness. I'm going to run this in the split loom up to the firewall and then run bundled wires behind the dash.

the wires are 16ga and since they are all green i put labels on both ends to help put them in the right spot

i ordered some of the connectors, here are the ones for the transfer case. i'll need the pins for these too and then i won't need to swap the switches. i included the part numbers in the pictures for reference

here is the transfer shift motor and ADD motor connectors. you can see that those black things around the pins slide out when you insert the pins in the connector.

finally the 4wd controller came in today too.

Nice work on the harness! This is going to be an excellent reference thread. Keep up the good work.

caligula455 · 07-01-2008, 09:50 AM

i have a connector pin update.

the good news is that the pins are available from toyota as a "repair wire" which has the connector pre-cripmed to ~4" of wire. part# 82998-12750 is for what they call the type "C" pin which is smaller than what i need. not sure of the other repair wire part numbers for the larger pins.

The bad news is that the connectors are ONLY available as the "repair wires" and that they are $13 A PIECE!!

i'm trying to find a compatible pin from TYCO or AMP who make most of the connectors for toyota. i'll post what i find.

zlathim · 07-01-2008, 10:02 AM

Ouch! I hope you can find them from one of those other sources. It would be better to get just the crimpable pins anyway. Only 4" of wire might make it hard to stagger the connections enough to avoid the "snake that just ate a rabbit" look to the loom.

Good luck, I hope it works out in your favor.

just a quick update:

the past couple weeks have been crazy busy at work plus two weddings and a Bon Jovi concert means i haven't done much of anything on the truck.

the one thing i have done is plug in the 4wd controller and turned the truck on. the 4hi and 4lo lights both blink on the dash buttons and on the instrument panel. looks promising for everything plugging in and working, i'll let you know what happens when i get the wiring harness done.

also it has been suggested to me that i buy an engine or body wiring harness from just about any Toyota or Lexus. there are only a couple types of pins and they are common to the entire Toyota range so any given harness should have plenty for me to use. any one have an engine harness they don't need? doesnt have to be from anything in particular, just a Toyota.

more to follow soon, looking forward to digging into the real mechanical stuff again.

actually, I was just at Radio shack, and they have nice female and male connectors, CHEAP with the un-crimped pins in them. 6, 9, or 12 pin available. I think it was less than 8 bucks for a male/female connector set... might work better for ya then reusing connectors.

the reason i need the harness is to get the pins to insert into the existing wiring harness connector (see a few posts above) and to connect to the sensors and motors on the transfer case and differential. looks like i have a line on a 4runner engine harness that should do the trick. i may need to put some connectors in just to break up the harness into reasonable lengths, so thanks for the RS tip.

yeah, I re-read that later on, but didn't edit my post. sorry haha. but is still an awesome project.

caligula455 · 08-14-2008, 05:15 AM

Another update:

Things have continued to be really hectic, but I received my parts from Inchworm so now i have another front dif wiring harness (from an '08 FJC but same connector) for the transfercase motor, new switches for the transfer case, a new speed sensor for the case and a speedo signal converter to adjust for final tire/gearing.

i'll get pictures up soon, hopefully tonight and start installing parts soon as well. i should have just about everything to get the front end wired up for good and put the transfer case in teh bed of the truck and shift into 4HI and 4LO using the buttons on the dash.

anyone want to help install a transmission or rear gears some time soon?

zlathim · 08-19-2008, 07:57 AM

Are you doing 4 wheel burnouts with that thing yet?

unfortunately, no. I'm really struggling to find enough time to spend on this project right now. i should have some pics of more electrical progress soon and then its back to spinning wrenches.

zlathim · 08-20-2008, 08:38 AM

I hear you, budgeting time is harder than budgeting money sometimes. Here's to hoping you find time to get after it soon

Humm3071 · 09-07-2008, 10:50 AM

I hae do this swap to my 2006 tundra since i bought i cause i am loosing so much for a trade or ot right sale. If we could keep in touch maybe i can get some guidance i get a lot of good info form the references youput on here andim amtryign to go low budget just the same so let me know
thanks

Humm3071 · 09-07-2008, 10:51 AM

dont mind the spelling i acc. sent it lol

drguitarum2005 · 09-07-2008, 11:16 AM

looks like you made a lot of progress but man i hate dealing with wiring! i'm thankful that mine is fully manual with the exception of the ADD. any new updates?

caligula455 · 09-08-2008, 10:09 AM

a little bit of progress to post. I've been holding off on everything else till the wiring was complete, and the wiring had been waiting on getting a harness to pull pins out of. I just won and paid for an 98 camry engine harness of ebay so that should be here soon and the wiring will get finished up once and for all (i hope).

the front diff ADD motor harness from the '08 FJC does fit perfectly on the transfer case motor, so that is good news. it basically looks exactly like the one i cut up earlier, but is about 8" long instead of a couple feet.

in other news, the transmission mount i got doesnt fit quite right, but is close enough i think i can make it fit, but it will be a little shorter when the "wings" are bent out to match the angle of my transmission mounting surfaces. this will make it a little shorter, but hopefully it will let the t-case front output clear the cross member.

also i tried to mount the tacoma VSS, but the gear is too big to mesh with the gear in the transmission. there were two styles of VSS, early and late, one with a slightly larger gear diameter than the other. i'll have to check the with Jim at Inchworm and see if he sent me the bigger geared version (i think he did) which would indicate that i need the small gear version.

a better update with pics of all the wiring details will be up soon when i get my harness from ebay.

First off I want to say excellent job. Down the road I'd love to do this to my 04 Sequoia. I've regretted not getting a 4wd but they didn't have any 4x4s in Marlin Blue Pearl which was what the family wanted. When it's not everyone's favorite, it'll become my newest 4x4.

I have a question on the wiring. Is the one connector you need the harness for the only one missing the wiring? Is the wiring to the cluster and the switch panel and TCCU complete? If so, would it be simpler to find a wrecked Tundra/Sequoia and pull the 4x4 harness from it so that everything is a complete drop in? I'm assuming (I know, make an ass of me) that the picture that is 'missing' the wires is the one that goes out and controls the 4wd system outside the body.

I'm impressed that nobody has told you to sell it and get a 4wd Tundra. Even though this is a lot of work you have something you can be proud of.

Thanks.

yes, the plug that i show the blank pins in is the only one missing the wiring. the dash side to the console buttons, gauge cluster, ECU and 4wd controller is all complete.

it might be easier to replace that harness with a 4wd version, but it would be expensive and i would rather just run the extra wires to the 4wd parts and not have to re-run all the other parts of that harness.

p.s. still waiting on my harness from ebay.
