Help on passenger side engine bay Dewiring

I have 3 wiring bundles to go through. I see these plugs just laying in the engine bay with nothing to do! So off with its head!

First up I have this little bundle. The plug the furthermost out has LY/LB going to it, and the wiring diagram says that goes to the washer motor. GONE.
The second wire is BW/BLg, and it is the sub zero motor. GONE.



Next little bundle comes from the firewall. It is right beside the AC ports, and it has 2 bullet connectors on it. I have traced the wires across the firewall and to this side of the drivers fender:




I have literally NO clue what those are, but would like for those to be gone as well.

Last wire comes off near the headlight motor.

I believe it to be the headlight cleaner motor plug? Since I have a US Spec model I can take care of that too.


I just want a double check with this, and find out what the 2nd set of wires coming from the firewall do. I am not too good with wiring diagrams so I may need some help on it.

Another Dewiring thread: Ignition coils

So I have no need for the stock ignition coils nor their wiring. This is where I sit:



I know, it's a huge bundle! Let me show you what I need to keep out of all of that:



Bottom blue wire = Tach signal coming from MSD box
Top red wire = Signal for MSD box


Ground and Signal wire for E-Fan, respectively

The only wires I would want to keep would be a power wire for the stock coils (to keep it as a signal for the MSD and E-Fan) and the YG wire (for the tach to work).

Now my question is can I clean up all the spare wires left over?

EDIT: Yes, I know. Corrosion. It's getting all cleaned up and the battery relocated to the rear soon.

Is the one relay for the hot start motor? I don't have that on my SA. I removed all of the emissions and carb wiring. Much cleaner!

Stu I think the bullet connectors are for the AC relay but I'm not sure on that.

BTW, you better get good at reading the wiring diagrams. All the answers are there usually, just have to dig dig dig until you find it.

That is what I am aiming for. Nothing on that side of the car but the headlight wiring and brake booster/line

Looks like it's getting the boot! I hope it does not turn the AC light off from the fan ****. I kind of like that.

if you have an 84-85 (maybe 83 too?) there is a washer motor and level sensor set of wires, so that's 4, add in cruise control, and the ac and the sub zero and um that is more than 4...

It's an 82. I just got done removing the speed sensor wire for the cruise. I haven't had cruise control on here, it was on when I got the car but I swapped the motor and threw away the unit.

No AC, No Sub Zero or anything. I will find out what wires those are and pull them from the plug in. I cut the wires and left a bit around, so when I go get the harness I know which ones to remove first.



Also, if my memory serves right, this bottom hard line was for the charcoal canister? I will be removing it as well and plugging it near the tank.

You'll want to keep that charcoal line open to vent the gas tank. I just removed it all the way back to the gas tank and left a foot or so of soft line dangling.

2nd gen strut covers FTW!
