zthis Posted December 29, 2003 Share Posted December 29, 2003 Can i remove the stock transistor ignition unit from a 1975 280Z (V8 with an autometer tach) it currently has only two wires connected Black to ground and White which only seems to go to a test plug. Also anybody know what the single red wire that enters the back of the speedometer through a rubber grommet is for ? Quote Link to comment Share on other sites More sharing options...
love-my-V8-280Z Posted January 10, 2004 Share Posted January 10, 2004 Please let me know how it goes when you remove the ignition unit, I just placed a post that asks almost the same thing. Quote Link to comment Share on other sites More sharing options...
love-my-V8-280Z Posted January 10, 2004 Share Posted January 10, 2004 My print shows the red wire from the Speedo going to the floor temp warning lamp, on used in Califonia cars,,, Good Im glad I don't live there! 9% sales tax I heard and tons of government regs that all cost more of our money!

GAZRNR Posted January 12, 2004 Share Posted January 12, 2004 I am wiring up my 78 now for a V8 and working thru what to use and what to snip. I removed the transister ignition and all the relays behind the fusable link mount. I also removed the fusable links and will use a fuse block in their place. So far I can't believe how many wires are factory spliced into the stock harness. There is a pile of wires when you skinny the harness down to what you will use. I am using a fuel pump oil pressure switch per JTR. The use of a painless wiring fuel pump 30 amp relay kit and MSD box alter the configuration slightly from the diagram in the book.

love-my-V8-280Z Posted January 12, 2004 Share Posted January 12, 2004 Gaz, Thanks, have u started the car yet? There are several other relays that are for the fuel pump above the fuse box, have u bypassed them? Are you just following the JTR manual or studing your wiring scmatic?

GAZRNR Posted January 20, 2004 Share Posted January 20, 2004 Terry, I removed all the relays under the fusible links. Replaced the links with a fuse block. Using the datsun service maunal, which is not as much help as you might think (my ability to read the diagrams) and the JTR manual for getting the engine bay wired. I am using a fuel pump realy kit, oil pressure switch to fuel pump. The addition of an MSD AL6 box and MSD distributor adds to the process but not all that much. I have not yet finished fitting the harness. I saved the removed relays knowing that A/C wiring will be a challenge at some point. Once It get it figured out and working I will post my results and include what color wire I ran to each item. Rusty Quote Link to comment Share on other sites More sharing options...
