ok..... need some help here..... i'm pretty mechanically inclined, but electrical..... forget it. i knew going into this that this would be the hardest part FOR ME..... i spent 6 hours today trying to figure out how to wire the chevy starter using the stock jeep wires..... is this possible???? if not, what do i need to do short of installing a button for it?? and please..... make it as idiot proof for me as possible.....:fish:
 
#117 ·
i still have the jeep starter wires going to the chevy starter, works just fine!
a lot easier than running all new wires IMO.
as far as how to do it, i just used the existing wires that went to the jeep starter, and connected them to the chevy......maybe 15 minutes?:rofl:
shoot me a pm if you need anything specific!

ok..... my chevy starter has 2 studs, 1 big and 1 small. the original big red wire straight from the + terminal on the battery goes to the big stud. correct?

then i had 3 small wires on the jeep starter..... they go together?? one runs up the harness to a connecter, the other 2 wires go into the same little connector at the starter. one wire goes up the harness (i think to the alternator) then the other goes back to the plug that was on the side of the AX-5 i took out..... possibly a neutral safety switch?? if it is, it never worked anyways. sorry if i sound like a :newbie:, but like i said..... electrical ain't my thing!:2thumbsup:

yeppers, dump the neutral safety switch, and wire it exactly as the jeep starter was wired. i dont think i have a connector going from the starter to the alt though, but i am getting old i guess.....and it was last year for gods sake!:rofl:

bear with me! :D so the three small wires..... one is by itself, the other two are on the same connector..... can i just cut the one that goes to the neutral safety switch and leave the other onehooked up?
 
#122 ·
i think what i did on mine, was trace the wire from the ignition switch itself, tha twent to the starter. then put that onto the small connector on the chevy starter.
the big connector will goto the battery.
i dont "think" i have any other wires from the jeep on there. there was 1 wire from the painless harness that went to the starter, but that was it.
so i guess yes, just cut the neutral wire and give it a shot!

I had to bypass the stock starter circuit, the Chevy V8 starter would overload something in the stock jeep wiring and if I cranked it longer then a second I wouldn't be able to crank it again for a half hour or so, I was always jumping the starter with a screwdriver until I bypassed it.

This is going to be my last resort, so bottom line is you ran a wire from battery to distributor with a switch to cut power. then ran cable from battery to big post on starter, and wired from one post to the other (on starter) with a switch for starting. correct? what gauge wire did you use for the starter? dist?
Thanks!:cheers:
 
#127 ·
Yep, I have a 12AWG (IIRC) wire from the battery or fuse box (I don't recall) to a switch in cab that goes to the dizzy.

The push button switch also is 12awg (IIRC) and goes from the fuse box to the push button to the small post on the starter.

The battery cable goes from the large starter post to the battery.

thanks martin!!! i had them hooked up like that at least 7 times yesterday..... all a no go..... got to picking around at it today..... realized when a friend and i were pulling the 4 cyl, i asked him to unplug sensors and stuff..... well he unplugged EVERYTHING..... hooked a big plug back together and voila!!! cranks with the key!!! definitely shooting for firing up this weekend!!

list of things remaining:
exhaust
trans cooler
electric fan switch
modifying skid to accept trans mount
fill anti-freeze
fill trans
wire fuel pump
mount power steering pump
have alternator converted to a 1-wire setup
belts


i think thats it!! we'll see how it goes!
