I cut my wire harnes completly in half cutting through the foor and I can't tell which of the 4 wires go together, or which of the 2 tan wires go to the 2 I have to connect.
Not familar with american motors but i would hazard a guess and assume they are for the lamba sensor ,now the 2 white wires sre for the heatrer on the sensor so they can be connected anyway around but the 2 tan wires have got me as a lamba sensor uses two different colours for the filament in the sensor a gray and black is normal but it can vary although i have seen two black and two grays on some replacement sensors so just connect them up and if iam correct it should work providing that this is the lamba sensor wires you have cut through ,if iam right and the engine symbol light comes off reverse the two tan wires and clear the fault code and try again

on the top side of the transfer case near the shift arm ....there is a transfer case indicator swtch.... connect into the only brown wire on the switch.........Be sure to solder the wires together, scotch locks are a no no ,, will corrode and cause intermittent connection, wich can result in other 4 wd component damage

sounds like you bought the male trailer side,the trailer side comes with an additional white wire for trailer ground,sounds like your already wired for trailer lights
SOURCE: i have a 1995 gmc sierra 4x4. It blows
The short is inside the trans, but you will need to take the pan off and trace each wire to find out where the short actually is. You have narrowed it down pretty well. One way to really narrow it down before you take the trans out is to unplug the connector and put battery power to the PINK wire cavity. Now take a jumper wire with a 10 amp fuse and touch each wire until the fuse blows. The TAN/BLACK is the Torque Converter Clutch solenoid. BROWN is the 2/3 shift solenoid. Lt. Green is Shift Solenoid "A" and YELLOW/BLACK is Shift Solenoid "B". Those 4 solenoids are powered by the Trans Fuse.
Testimonial: "great info...helped me find the trouble"
There is no remote wire on these newer trucks....03 and up....u have to buy the harness....although i didnt....i have an 03 gmc sierra and just pulled the schematic and matched the wires. And there is no programming to do on an aftermarket stereo.....I work for GMC and we cant program aftermarket stereos......if u buy the right harness ...and its over $100 then everything should work just fine.....and this does not disarm ur alarm system either....mine still works fine....hope this helps
SOURCE: IAT sensor has 5 wires,
IAT is tan for signal, black for ground. Other wires are probably for the MAF.
