We sell one for E38 cars and trucks but nothing for the older ones. Not a big enough market and not easy to make work with all the different options.

I think jolt and maybe someone else makes a harness just for piggybacking a terminator. Built to your needs.

4th gen Camaro ECM uses a Micro-Pack 100W terminal. It will literally plug into a Holley ECM connector. Some of the dimensions are different but all the critical dimensions are same within tolerance. I have all the connector and terminal part numbers if you want to give it a try.

You'll have to splice together all the 5V reference wires, and same with all the sensor grounds because that's the way Holley does it. But it's all doable if you're willing to put the effort in.
