Okay cool. So I should be good keeping only cruise and a/c associated wires? No need to keep speedo wires?
I think this may be the last question I need to ask for a bit lol.
If I remove the speed sensor wires, how do I hook up the speedo in the cluster? I think that may be explained in that 1993 wiring link that you posted above though.
my damn laptop isbeing a pita, so this is from my phone.
i pulled all the wires from the ecu connectors. i think i made a mistake though. when i cut the 1 dk grn a/c wire, i followed it snd cut off the line pressure plug. i followed the 2nd wire from the pressure plug and it went to the front plug for the factory a/c compressor.
is the a/c still gonna work? im afraid it is not gonna work. i also screwed up and cut the white cruise wire off at the firewall. is that a problem either?
Not sure about a white wire to the cruise control. I'd have to look at my setup to see how I have my A/C wired but its not going through the PCM. That may be something new in 94 but mine is wired directly from the dash to the compressor.

there are 2 plugs on the compressor, one in the front and one in the rear. I would just hate to find out that I killed the a/c from that 1 wire, and now it is going to take a bunch of work to put it back together and make it work. Really, I dont think it needs but the 1 plug, but I am unsure about that.
E12 and B10 were the 2 wires Im concerned about. I guess I will revisit them at a later time.

Thought you said you had a sanden 1 wire compressor? You may have to keep the stock PCM in the truck to monitor compressor pressures. Haven't ever had to deal with that since both of mine went to a Sanden compressor.

The plug on the back is a pressure switch that you won't need. So you can supply power to one terminal on the front plug and ground the other one to make the clutch apply.

Damn...
No, nothing aftermarket, I notched the frame for the stock a/c compressor to fit...
Awsome, so as long as I have the front plug then I am good? Thank God! lol
Don't be scared, start yanking wires!!!The ONLY wires i kept from the 91 is to the tail lights and to the fuel pump.

Its all done now lol. Tonight I am going to finish gutting the 2002 fuse box and hopefully start hooking wires up. I need to go pick up some wire, some terminals and hopefully I can get it cranking this weekend. After I do that, I am stuck for 2-4 weeks so I can buy a fuel pump and credits so I can start tuning.
