    The closest thing I can find is the C219 part in pic 2 but the wire colors are not exactly the same.

    It seems that’s it, the only difference is in the drawings the wire colors don’t match up. The other weird thing is that the Letters are the same as the ALDL

    The Blu/Wht could be Ppl/wht too, which goes to ECM “fused”

    Just speculation, on the connections, but the Tan/Blk and the BLU/WHT wires coming off the ECU connector have no where to go. I did find another same Color Blu/wht coming off the DRAC module that also goes to ECU. In the Diagrams the Tan/Blk wire is used for Torque converter clutch, HEI...

    Could it possibly be a Radio/antenna component? or my first guess was a brake assist module for trailering.

    It’s a small chip, connected to the wires. The box had electrical tape wrapped around it which I removed.

    Help! ID this electrical component.

    Yes it was inside, and possibly a connector for the ALDL. Unfortunately the previous owner had really messed up the wiring inside the cab, which is why I relplaced. Luckily the engine bay wiring was unmolested, and the Burb runs great. I’m just worried that this part my have something to do...

    The doner Suburban did have marker/running lamps on the roof. I may have mixed the part in with the old stuff when I laid everything out.

    Help! ID this electrical component.

    About 99% done installing a new harness in a 1990 Suburban, and came across this small grey box with a circuit inside. It has the letters FEDCBA where 6 wires come out, which seems to be the same as the ALDL connector. 2 of the wires (Tan/BLK, and BLU/WHT)seem to go to the ECM, but the other...
