I have a 2000s cheby hei module with the 4 pin connectors oem they have 4 wires coming out, also im going to use a 80s ford coil and ive adapated the distributor for electronic ignition. Question will I also need a relay an if so how will i hook it up with a simple set up?

Gm part number GM 089 5A21

Read the HEI upgrade article for particulars and details.

I did but i didnt seem to find about the 4 pin connector

The entire article is about the 4-pin module… ¯\_(ツ)_/¯

Would you recommend adding a relay to the mix?

Others will probably recommend one but I have 3 vehicles running without them and all have 13+ volts at the module. Been running them for 3-8 years

I used a Delphi DS10071 module about 4 or 5 years ago. I have a couple of supposedly real AC Delco 4 pin modules somewhere but haven't needed them yet. I intended to install a relay but have never gotten around to it. I used a NOS GM coil with factory mount intended for a late 70's Chevette engine mount. I mounted the bracket on the fender in my truck. Got a couple of assemblies on ebay. I've forgotten the GM part no. for coil and bracket, but the coil is equivalent to the SM DR35.
