at this point getting a new dash is sounding better mine is cracked anyway. Then it makes things later easy cause everything would just be for a 91 truck.

now wires in my 89 2.9 headlight harness first wires no mates yet or not used.
Tan/lt blue:3-4 shift solenoid (a/t)
pink/lt green: not listed on 2.9 diagram but shows as a test connector on the 4.0
dark green/yellow: coil resistor (2.9 only)
Red: not sure
white: to cruise control?
black/white:goes to multiple things
white/black:to clutch/ neutral switch.
The wires that are mated right now from the 2.9 to 4.0 are the color matched wires
there are 2 red/lt green: 12v power
orange/black: volt meter?
solid green or maybe a lt green: not listed but I think its for the brake switch.
To get the truck to crank with the key I took the red/lt blue and pinned it with the solid pink in the 2.9 harness
...Like i said its running on 3 maybe 4 cylinders 1,2 and 4 are the coldest. The nice thing about having the jba headers is being able to kinda check like that.
