Thread: Missing Wire

  1. #1

    Default Missing Wire

    I was wiring up the relay ad found there was no red wire that goes to the #30 relay terminal. The wire is shown in the schematic, but does not exist. I've highlighted the missing section in red. I'm going to assume I need to splice into the WBO2 harness to add this. I wish I had known this before I installed the harness.

    That's a bad drawing in black & white, hope it looks better in color.

    The RED battery feed is drawn going to #87, and #30 goes to the fuel pump on Green/Black. Do you have the 4 wires for the fuel pump relay? Gary

    Gary, the black and white drawing is from the C950 installation manual. I highlighted the missing wire in red. The wire is shown in the C950 install manual, but it's missing on my harness. The wire I highlighted in red goes to #30 (but is not on my harness). The red wire that goes to #87 is on my harness (as is the green/black #85 and the black to #86). In the manual, under "5.1 Step-by-Step Wiring Harness Installation" there is no mention of this wire.

    The manual also says "the relay holder is about 3 feet from the ECU connection". There is no relay holder on my harness.
