87 TBI oil pressure sender wire

[Johnathan S]

I’m sorry guys I know it’s probably on here somewhere I tried looking. I just did an engine swap on my 87 R10 and I went to a carb instead of TBI. I just need to know the color of the oil pressure sender wire for the gauge so I can jump it from the fuse block. The original engine I pulled out had a switch for the fuel pumps behind the distributor and the sender wire by the starter and I buried that wire in the engine harness.

It’s green just like the coolant temp sensor wire. I had to mark mine to keep from mixing them up on the engine swap on my 87 I did last month.

It's tan on my 85 C10 that I switched from a 6.2 to 350 with a carb.

It’s tan on my 87 suburban with a 6.2. But he has an 87 tbi which is green like I said. I have 3 87 tbi trucks. All are green.
