Booger Posted September 16, 2019 Report Share Posted September 16, 2019 (edited) Hi everyone, I have a 72 Datsun 510 with a S14 SR20DE. I purchased a Wiring Specialties Pro Series Conversion Harness for it and I need a little help. So, I followed the instructions and I got the car running....however my Chassis Connector interface (picture below) doesn’t seem to work. I have labeled all the wires (tach signal, check engine light, fuel pump trigger etc) isn’t working. So I bet ur wondering how I got the car running if I can’t get the fuel trigger wire to work coming from the Chassis Connector? Well, I wired the “hot” wire from the fuel pump straight to my ignition So I knew the fuel pump was working and the engine runs just fine. Having said that, I can’t seem to get any of the pin-outs to work (pin 1-20/and pin D for fuel pump) tho. Does anyone have any advice or info on these wiring harnesses? It’s pretty straight forward...and I thought the hard part was done...but I ran into a snag. Just to be clear, I can’t get the following to work: gauges/fuel trigger/alt light/oil light etc. I spent hours and hours trying to figure this out. I know I can wire up all the gauges individually straight to the source, but that’s defeating the purpose of having this harness. Any help would be great.

Don't the old harness have the oil lights, alt ect...? fuel pump would be thru the relays(the BLK BOX type) to power via the ignition switch Edited September 16, 2019 by banzai510(hainz) Quote Link to comment
