79280zxjojojo Posted February 27, 2014 Share Posted February 27, 2014 I just bought street fire (5520) for my 79 280zx n/a and I've search on how ther wiring diagriam and I've only came across this which is the 6al diagram. Now with the msd box do i hook up the wires with factory to give it amp ? or do i disconnect the factorys wires and hook up msd? Also would i need the tachometer adapter from msd ? Do i use the green/purple instead of the white wires and connect the green and purple to B/c on the e12-80 ? Quote Link to comment Share on other sites More sharing options...
audiofreak97 Posted April 3, 2014 Share Posted April 3, 2014 quick and dirty Tach Adapter: Yes Orange and Black to Coil + and - Red and White to the + and - that you removed from the Coil to hook up the Orange and Black (tach adapter runs parallel off of these red and white wires) Heavy Red and Black to Battery. Gray wire - not used Quote Link to comment Share on other sites More sharing options...
