Re: Tbi swap build thread

GM to all from wet So-Cal

This morning I had a bit of free time - here is headlight circuit diagram for CUDA using remote relays to switch headlight circuit. Use BOSCH style relays and 12 (or 10) AWG SXL (SAE J-1128) automotive grade wire to bring current to your headlights. On relay control side you can use smaller gauge wire (16 to 18 AWG) to make harness a bit easier. Unfortunately, many use commonly available THM grade wire which is not suitable for automotive applications due to extreme temperatures. Make sure to use weather pack style inline fuses or fuse links! Absence of fuses can lead to fires!

Ignition circuit and ECM interconnect is to follow... Hmmm we are getting lighting and thunder here - very unusual!
