After 6 months, finally putting the finishing touches on the engine & ECM/wiring harness install.

I was in the process of hooking up the other harness (not sure what you call it - underhood or body wiring, it's the harness that plugs in near the steering column and contains the wires for the tach, starter, etc.).

I have just about everything hooked up, but I have three connectors left on the other harness and I have no idea what they go to or if they are even needed any more - in addition to swapping the ECM to the '730, I removed all of the air conditioner components.

See pictures below. The three connectors are:

Connector 1: Two wires, one black and one green. Terminals are perpendicular to each other. Long wires, stretch over to the passenger side and then some. Maybe something A/C?

Connector 2: One red wire. Seems to be about the same length and along the same path as the two starter wires.

Connector 3: 4 wires. Might be a relay harness?

If anyone can help me identify these I would much appreciate it. Thanks.

 

i think the green and black wired connector may be for the ac and the soild red might be the under hood lite

 

I thought the green and black was A/C, too. That makes sense.

The red one might be a hood light, but I thought that the people that had the car before had cut the hood light. Maybe not, though.

Thanks for the response.

 

In that case may be a power feed that came off the batt terminal on the starter motor ?
Early cars had some feeds from there

 

That is entirely possible. Unfortunately, someone at my brother's shop threw away my old starter so I can't look at see what type of connections it had on it.

There are two wires (separate of this one) that go to the starter - one large, one small. Both have the type of connectors that go over a stud. The new starter I have only has one stud (large) and then a spade type connector. I assumed I'd have to cut the end of off the small wire and replace it with a spade type but now I'm not sure...

 

red looks like a power connection for the AC under the hood as Ive seen that wire hooked up to the ac somewhere in these cars. Could be wrong but ill look at a harness I got here when I get a chance and get back to you. never seen a starter wire that looked like that either

the last connector is for the wiper motor as its the only "L" shaped connector on the car

 

Is it purple?
That is the starter wire from the ign switch that makes the starter work ;
goes on the starter solenoid ( small ) terminal
Factory starters had stud terminals for all connections

 

I believe it's purple; it seems pretty faded though.

The aftermarket starter I bought only has the one large stud terminal; the only other terminal is a spade connector.
