I have some time on my hands as I await the install of a new 455 engine to replace the 350.
The car is an automatic w/ TH400 trans

I replaced the much needed Rear Body Intermediate and Tail Panel Trunk Wiring Harness. (I bought this from Motor City Muscle Car via EBAY and all wire colors match perfectly with original existing

With all that said the rest of wires are like some 54 years old and I'm going to update the rats nest.

QUESTION- I have HEI ignition so is this option realistic in a complete harness or does this need to be modified.

QUSTION- Should I change all switches too? ( I have a feeling this was dumb to ask I'm sure it would be wise)

Question- Please recommend good seller to purchase all that I need to re wire the Olds.....


As always...so many of you members have helped me out a lot and I appreciate all of you and the shared knowledge....!!

 

I have had excellent service for some of my wiring requirements on my 66 Cutlass. Check out Electric Limited in Bedford Park, Ill. They did my ignition and battery cables. Excellent product. Check out their web site.

much thanks!

 

There is also American Auto Wire and M&H Electrical Fabricators.

 

I used M&H for my forward light and engine harness, which is everything under the hood except the A/C harness. I ordered mine configured for HEI and internally regulated alternator so no modifications needed.
