(1977) Off the connector were the relay once was maybe? if so wich wire is it? My diagrams are faded as hell.

rhettro74 Posted May 24, 2006 Share Posted May 24, 2006 Hey did you get your Fuel pump wiring finished if so can you let me know how you did it. I have a 77 with an 82 ZXT engine and Engine harness Also are you using a Relay for the Fuel pump if so which one the 77 or the 82 and how and where do you plug it in. All the best Thanks for the help Quote Link to comment Share on other sites More sharing options...
HB280ZT Posted May 28, 2006 Share Posted May 28, 2006 I have a 77 280Z also and what I did was run a new wire (12 gauge) to the pump from the relay box of my MS. However prior to that I used a relay to power the fuel pump by hooking the old pump wiring to the relay and a new 12 gauge wire from the battery. I also helped the ground wire by using a 12 gauge wire off of the pump to a good chassis ground and then adding the original pump ground to that ground point. Also I am running an MSD fuel pump and it works just great. Hope this helps. HB280ZT Quote Link to comment Share on other sites More sharing options...
2802NR Posted June 12, 2006 Author Share Posted June 12, 2006 I used the MS relay board so I eliminated the stock fuel pump relays under the dash. When you do that you end up with two white wire harness connectors hanging from under the dash. all of the wires are useless now without the stock fuel injection except for the power source for the fuel pump which is where I tapped in. If you follow the wiring diagram posted by trwebb26 it is easy to find. Its much easier than running a new wire IMO. Now if you are wanting to use the stock relay instead of the MS relay board than I'm afraid I cant help you there. Good luck. Quote Link to comment Share on other sites More sharing options...
