Sorry for the delay guys, Im neck deep in a fidanza/centerforce 2 install. I designed this for my 75 280Z, will work with all others the under dash connection might be different between the years.
I built a "engine" fuse and relay panel mounted on the drivers side inner fender. The MS2 is mounted in the same place as the orginal ECU, and I am using a innovate LC-2 wideband O2 sensor, and I used a 8ft MS2 harness from DIYautotune. I have a master parts list including prices for what I have done if anybody wants a copy of that.
