Looks like you didn't have to travel too far. What a mess.

Agreed. Now to figure out what all goes where. And try to put it back together. I think the issue is the red wire that runs that loom back to the pass side isn’t getting power and red is usually pos

RED w/trace can sometimes mean it switched B+ (relay, switch etc).

This one has no trace. It runs back to the oxygen sensor heater relay.

88 Electrical Manual shows no RED going to O2 Heater Relay. 88EM should be the same for 89.

is there one for the a/c relay?

Only RED I see is as follows:

Fuel Pump Relay pin1 (30)

B+ Latched Relay pin1 (30)

Cooling Fan Relay pin1 (30); opposite side of vehicle.

Update. Pulled all relays(5) from engine bay. Bench tested for activation as well as OHMs. All tested between 74-78.5 ohms. Cleaned relay connections and wires. Pulled the looms back on driver side, from the relay harnesses that goes to the firewall to the fuse block and the one that goes to the oxygen sensor heat relay. I checked and cleaned the wire for the Ballast on the starter relay. Cleaned up and made new connections where had been spliced previous. Couple spliced wires that make no sense. E fan is pulling power from grey plug attached to EGR connector. But only comes on when key is on, AND with the hot wire from Fuse block.

Quick question. That might help. Running a multimeter on the starter relay, should I pull 12.4ish v on the Ballast resistor terminal with ignition on?

With KEY ON, voltage for 2-3 seconds only. Is your Relay Block one piece or can you separate them?

I can separate them into the 4 separate ones

Okay. Looked like one piece.

So another update. Wired everything back up as previously done. Loomed everything and taped everything. Especially connections with butt connectors. Now when I turn the key over the fuel pump will prime as before, the efan will turn on as before but now my AC clutch engages. Even when pulling the ac clutch relay it still does it. Didn’t do this before.

So that would explain why the ac clutch is now clicking. When It never did it before what did I screw up
