66 C10 Engine Wire Harness w/ Gauges and HEI

[Shtudwn]

Hello,

I'm in a quandary that maybe someone could provide some advice.

I have a 66SWB that was originally equipped with idiot light dash. I have since replaced that with a stock dash that has gauges. The truck now has a 350V8 and an HEI distributor.

I have been running on a hacked up engine harness and separate wires for the HEI and aftermarket Temp, Voltage, and Oil Pressure gauges but want to utilize my newly install dash with gauges.

I have purchased a Engine Wire Harness w/ Gauges and HEI for about $80 but am leery about opening the package and installing fearing that it will not get me what I need.

Question: Since my truck came with lights and not gauges, will this engine harness even work or will I need a different interior wire harness? If so, that might not be the direction i want to go because ultimately I want to go with an Autowire harness and completely redo the whole truck.

Ideas? Thoughts?

Thank you.

Dan
