Hey guys, I see the wiring diagram for the 4 prong plug on the 700r4, but its been 6 months since I had mine out and I only 1 of the 3 ways is soldered together, the other two look like they were broken before hand, when I was already driving it. So, I'm seeing that I am using terminals A, B, and D on the connector.
According to this diagram, A- (the only one that's connected to the truck wiring harness) is 12V brake switch to solenoid.
B- (not hooked up) is ECM and D- (not hooked up) is ECM ground to TCC solenoid.
C is not used.
Out of the 3 prong harness connector that connects to the truck harness, I have 3 wires.
A green wire goes all the way from that connector down to the 4 prong on the trans, but it broken.
A Blue wire goes down about 6", hits a 2 prong connector, and then a gray (faint olive green?) wire comes out of the other side of that 2 prong connector, and travels down to the 4 prong at the trans also.
The third wire, also a gray (faint olive green) travels from the 3 prong , to prong A at the 4 prong at the trans, but halfway down it splices with the other gray wire also.
So, to get my truck running, do I just leave the "A" hooked up and worry about the other two later, or does something else need to be done?
