Ok, Update. I stripped out the truck. It is a 1994 silverado with a 350 TBI/4L60E. I grabbed the entire underhood wiring harness. I cut the dash wires after the connector behind the glove box. I also grabbed the VSS Buffer and its harness. I labeled the wires at the ECM side and again at the termination end. Then I removed the wires that were not needed. This is what I have left:
ORANGE wire to fusible Link with ring terminal and splitters
Lg PINK wire to coil
Lg PURPLE to Starter Solenoid
RED wire to TBI INJECTORS (joins white wire to Injectors, 1 wire to each)
RED wire to Fuel Pump Relay(Research shows this goes to fuel pump prime connector?)
RED/WHT to Heated O2 Sensor
I also have wires that I am unsure where they run to or if they are needed:
WHITE from the Coil (I am sure it is needed but need to do more research as to where to connect it)
PURPLE Marked E13 split from Main E13 wire
From the Transmission I have:
a PINK wire that needs to go somewhere. NEEDS TO GO TO THE IGNITION SWITCH WITH A 10 OR 25 AMP FUSE.
From the ECM side I have:
E12 GREEN Wire to AC. (I may try to use this to bump the rpm for the winch, Leaving this coiled up for now)
E13 PURPLE (A splitter wire from the main E13 wire, I think I can just cut the stub and tape it right?)
E15 PINK/BLK-ECM ignition feed. This need to be connected to 3 AMP FUSE IN START AND RUN it feeds the ECM and further downstream?
E6 BROWN/WHT-Check Engine Light. Does this go to one end of the light and the other end of the light go to a ground?
From the Main harness under hood to the ECM I have:
BLACK/WHT wire Joins with A1 Ground. Can I connect this to a Ground on the VSS Buffer and the data link connector.
I also removed the Oil pressure wiring from the harness. The TAN wire that went to the instrument panel was cut out as I am using a mechanical Gauge. The ORANGE wire was connected to the GRAY wire to complete the circuit.
