I've been lurking around this site for quite a while now, and currently have my 2nd 3.4 bolted in to my 94 pickup (first one I pulled out of a wreck was NFG). I'm having a hell of a time finding any wiring diagrams as I can't get on to TIS without an American billing address. I believe that the donor motor is out of a 98 automatic tacoma, but I'm not entirely sure. The ecu is from the 98 manual trans taco that that I pulled the first motor from. The connectors from the auto plug right in to the manual ecu, anyone forsee any problems? Oh, and to kick the stress level up a notch, I need to have my truck up and running by monday, even if it means putting the 3.slow back in.
If anyone has or knows where to find the diagrams I need I'll send you a virtual beer or two. thanks
P.S. Elvota & mt goat, I'm holding you both personally responsible for my perdicament, as your build threads inspired me to take this on

 

Just to clarify, I'm trying to find schematics for the IK2, IK3 and IK5 connectors on a 98. And the IH1 and IH2 connectors on a 94 pickup.
Thanks

 

Will a 99 tacoma motor be the same?

pm me your email addresss.

Or try

not sure if they will be the same, but it's probably worth a look. I'll pm you my e-mail address as soon as i figure out how.

 

would my 94 pick up IH2 connector be the same as a 91 runner?

 

The auto plugs will plug into the ecu, but the wires are not in the correct location. You will need to repin the harness. The 94 and 91 plugs are the same, but again the wires are in the wrong location. You need diagrams for your 94 truck and for the 98 taco to make this work. Make sure check the part # on the ecu and find out the production date for it.

 

any idea where I can find diagrams for the connectors?

 

the numbers on my ecu are TN175000-9683 and 89661-04410 any Idea what year that makes it?
Also, how do I go about determining the year of my engine?

 

I will check the ecu #, as for the engine tho it wont be as important to know the year.

 

Thanks mate. I spent the majority of the day yesterday going through pages and pages of wiring diagrams for a 98 tacoma and trying to map a pinout diagram for the IK2 and IK3 connectors only to discover that they don't match the colors of my donor motor... DOH!!! (I'm doing a lot of this lately) I was told that the engine was a 98 and the stock plug plug wires on the motor say 98... Maybe it's out of a 4runner? Would that make a difference?

 

The ecu is 6 of 97 to 10 of 97. The wiring is differant from tacoma to 4runner also.

 

does that mean it's a 98 model?

 

Hey i got your pm.

Ill send you some of the wiring diagrams that i downloaded from TIS, but it was from a 99 tacoma motor. IDK If it will help you at all.

 

Thanks Mike.

 

I sent those out to you. Let me know if they help, or if you need more.

Where are you located? id be willing to lend a hand if you are local.
"edit" nvm: just rememberd you said you couldn't get into tis without an american billing address??

Good luck

 

99 and 98 are not the same

 

Good news Fellas, I'm reasonably certain that the donor is out of a 98 4runner, the diagrams seem to be lining up..

 

Yeah, I'm in Lillooet B.C. great toyota country. Well, the diagrams did tell me that my donor motor is definitely not out of a 99 taco, but I did manage to Access TIS via the In-laws card +address seems as though the motot is out of a 98 runner, NOT a tacoma, who knew they'd be so different. Thanks for the offer and the well wishing, I'll post some pics as soon as I'm up and running.

 

IT'S ALIVE!!! (sort of) it fires right up runs for 5-10 seconds then dies, any ideas?

 

Well, problem solved, I think... I swapped a few wires around and swore a lot, now the old girl purrs like a kitten at idle and roars when you stand on the throttle. Thanks Mike and Tim for your help. I'll try and post some pics soon, but first I have to finish packing and move to Vernon, (the maiden voyage will be a 3 hour drive) wish me luck!!!

P.S. If anyone is doing the same swap and needs the pinout diagrams I've made up, let me know, I'd be happy to post them and save some poor sap from spending hours and hours staring at wiring diagrams.
