1995 LT1 harness

[trackster]

Anyone have any experience and/or suggestions for an engine harness for a 1995 LT1 in a 1939 Chevy?  How many O2 sensors are needed?  Getting exhaust welded on Saturday and not sure if I need 1 or 2 bungs for O2 sensors. Don't have original wiring harness or exhaust manifolds.  Thanks for any info you can give.  Stay home and stay safe.

I used this site(listed below) when I was working on the GM throttle body system for the 1954.  You might search there for some information.  I would use the Painless engine wiring harness if I did another one.  You might check their site for the instructions for their harness (manual) and see if it tells you whether you need one or two.  (The other link below)

I installed a 95 LT1 into a 57 Chevy using a Painless harness. It fired right up, no problem.
