Alright guys I have a couple questions I picked my first old school Yota non running I’ve been working on it a bit firstly trying to get it started now my first obstacle was the battery I got a new one and re-ran new battery wires and terminals so it had a good connection went to start it and just the good old click when I turn the key the solution I think I’ve found is ordering a switch panel from jegs and just running the wire straight from the battery to the panel to the starter that should work right ? Starter is good.

second question is fuel I want to put a fuel cell on it but what do I do for a fuel pump with that ? Do I just wire the fuel pump from the cell to a switch and manually flick it on and off ?
All the plugs and wires distributer cap ect was already new

I could also use advice for suspension I want to keep IFS my plan with this truck is medium wheeling on the seasonal roads/trails through northern Michigan i could use some recommendations for lift kits control arms etc

locking hubs and clutch I want to get new locking hubs and a more heavy duty clutch for the trails

Any help/recommendations are appreciated if there’s anything else you guys have on your rigs that you now could not go without let me know thanks

 

Firstly, for the starting system: It should have a relay in the circuit between the keyswitch and the actual starter. IOW the wire should run from the battery to the keyswitch, then back to a relay which connects the battery to the starter when it's energized by the key. That way, the high current draw of the starter only has a short run, from the relay down to the starter. Make sure the relay is close to the battery. The shorter the high current path the better. Make sure the high current draw has suffuciently large cable from the battery to the relay, and then down to the starter from the relay. I believe I used a 2/0 cable, but I may be wrong on that. Maybe only 1/0 cable is big enough. Make sure the relay is heavy enough to handle the starter's current draw. The whole point behind this is to use a low current draw, battery to key and back to the relay,to control, but not be directly involved with, the heavy current draw, ie battery to relay to starter.
Do a search for Concicse starter relay rewire by RAD4Runner. He has schematics, parts lists, and so on for this mod. It's a great write up.

Secondly, for the fuel: You really should run the fuel pump off the COR (Circuit Opening Relay). That's a super good safety for running the fuel pump off. It atomatically shuts the fuel pump off it the engine sstops. Like in an accident. That way, if there's an accident, you don't keep pumping fuel all over the ground, with a real high danger of a fire. Dangerous to both you, who may be unconsious, and the first responders who come to save you. The factory fuel pump runs off the COR, so just use the power wire that feeds the OEM fuel pump to run the fuel pump you put into your fuel cell. Once again, it's a super good safety system. Very important, and fully automatic.

thank you for this that helps tremendously and I'm glad you told me about the fuel pump relay I did not think of that lol but a very good point id hate to be stuck upside down with fuel spraying everywhere.

 

Here is a good go to thread for re wiring the starter relay Circuit, lots of good info and explanation's it’s the one 2ToyGuy referenced. I re-wired mine with a painless wiring kit, you can go way cheaper but I wanted a good relay and good wiring and it was worth the extra cash.

That's the one! Thank you Discombobulated. Odd, that seems to be how I spend most of my life these days...discombobulatd.

Exactly the reason for the COR. And a super good reason it is. What if you're out on a trail, and manage to roll the 4Runner over? Even without someone coming along to rescue you, working on getting yourself out, when covered with fuel, can be a real problem. Nothing else, scary as heck. Stopping the flow can be a HUGE Plus. Leave it in the tank, where it belongs.
Like I said, there's one power wire feeding the fuel pump, run off the COR. It picks it's ground off the body metal, presuming the grounding setup is correct, so that's easy as heck to find Just make sure all the body metal is grounded to the battery as is should be. You might need to ground some thngs with a new ground wire, but it's an easy thing to do. Simple 12 or 10 GA wire, two ring terminals, and good to go. Your multimeter will tell the tale.

Good fortune to you!
