Well my car had a bit of a ghetto rigging job when it comes to wiring the ignition to the starter. Theres a wire that i found that goes from teh steering column directly thru the firewall (using the speedo cable hole) directly to the starter. I didnt know what this cable was for and had to cut it in order to take out the old speedo cable (since it was wrapped around the old cable). Someone told me that due to the color of the cable (white) it was probably for a radio or something.

I rewired it temporarily to get the car started, but now that i have new soldering skills would liek to redo it properly. Whats the proper way its suppose to be connected, and can i just redo it over properly running the cable in a more safer manner.

The car was automatic and now its manual, could that be why it was done this way?

Here are some pics

That is totally a homemade starter ignition circuit. That's about all I can say about that subject since I've never seen a automatic starter circuit/plugs etc.

On most cars (this is memory), the wire goes from the ignition switch...........to the interlock switch on the clutch pedal.................to the starter cut relay in the engine compartment...........to the starter solenoid.

I think it's a black/red wire from the ignition switch to the interlock switch, then turns to a green/black wire as it leaves that switch and arrives at the starter cut relay with those green/black colors and leave the starter cut relay as a black/white wire and arrives at the starter solenoid as black/white.

You'd really have to look at the wiring schematics in the free online FSM's to make sure I wrote down the right colors/plugs.

Two switches on the clutch pedal. The lower, tiny switch is NOT the interlock switch. It's the one almost at the very top of the pedal that is the interlock switch...............in indeed you have on on the pedal (swap and all from automatic).

Sorry, I'm too lazy to look at the FSM for the right colors right now.

Tell you what Bubba, go to your Trail coil and remove the three nuts that hold it in place. Now lift it up and out of the way. Leave all the wires on it.

Look below where it was. If you don't have THEFT protection on your car, you should see an electrical plug with a BLUE JUMPER connected to it. That BLUE JUMPER should have a jumper wire on it going b/t two sockets. Pull that BLUE JUMPER off the chassis half of the plug and see if the two sockets that were being jumpered are black/white for one wire and green/black for the other. Say yes, that's what you found, then write back what you found.

IF that is what you found, then the black/white goes to the starter solenoid. If you jumper 12vdc to it directly from the battery positive terminal, the engine should spin over and if the transmission is in gear your foot will/might be run over. That's life.

So say you found that condition. Now the other wire that is jumpered should be green/black. THAT wire should be coming from the interlock switch at the top of the clutch pedal's interlock switch.

That's as far as I care to go right now. You get the drift. Ignition key to interlock switch to starter cut relay (no real relay there if there's no theft protection) then to the starter solenoid.

Notice no white wire fanagled thru the cutout in the firewall? Ain't a supposed to be any, but does work, does it not? Yep.

Bubba? I didnt do this lol

yeah it still works. I will re-read your comments with the FSM at hand and try and do this correctly lol

Thanks

No offense meant by Bubba. I knew you didn't do it.

If the somewhat rectangular interlock switch is not there at the top of the clutch pedal (top couple of inches if memory serves), then don't worry. There still should be a plug on the wiring harness that goes to that switch. It will have two fairly large wires on that plug. One black/red and the other green/black. Jumper the two together to make that part of the circuit.

IF you do that, then that part of the circuit is MADE and now you only have to make sure the green/black is going to the Starter Cut Relay (or just a plain plug with blue jumper if you have no Theft Protection on the car).

So it's possible that once you jumper the black/red and green/black jumpered, you MIGHT get lucky and turn the key to Start and it will start.

I'm writing this with a lot of ignornace. I've never seen exactly how and where the automatic plugs are on a auto car. It should look like the FSM schematic though.

HAILERS

Aw shoot. There's a fatal flaw in what I wrote. The previous owner has installed that white wire and it's going to the starter solenoid.

Soooooooo, the question rises. What did he do with the original black/white wire that was on the starter solenoid in the first place?? It might sitll be there near the starter solenoid tucked away OR he cut its terminal off and you won't be able to find it in that area. OR???????

I guess if you wanted to do it properly you would look at the FSM and duplicate what's in it?

HAILERS

I done thunk about this for the last time and came to another conclusion.

I looked at the schematic again. I see (jpg attached) a plug called the Inhibitor switch (for A/T) with a reference designator of A-03.

At one time that plug attached to the auto transmission and inhibited starting unless you were in neutral.

So if that plug is still on the harness of your car (four socket plug with the wires shown in the other jpg attached), what you might do is jumper the BW with the Black/Red wire in that plug and then try to start the car. BUT you'd have to make sure the original Black/White wire at the starter solenoid was still there and attached to the starter solenoid prior to starting the car.

I'm guessing the other two wires in that A-03 are for reverse lights or something not worth talking about right now.

I'd attack the problem with this answer prior to doing anything with or about my other answers in the other posts.

Sorry about the confusion because I've never seen a auto car and I'm now assuming the starter cut relay will have the blue jumper there and so what I just now wrote MIGHT work.

Anyone that has done this can pipe in any time they want. I'm done (cooked).

One more thought somewhat related to starting. If in the past this car has been a pisser to start when the engine was cold, but started fairly well once warmed up, I might have a solution to that. You can see a Black/Red wire in that schematic and how it goes to the Emissions Control Unit.

That wire puts a 12v signal on pin 3B of a series four ECU only during starting. That signal NEEDS to be at the ECU especially during a cold engine start because it influences how much fuel gets injected DURING (and only DURING the start procedure) the starting procedure. Check that pin 3B out after you get the starter problem sorted out.
