z_drifter Posted October 28, 2011 Share Posted October 28, 2011 NEED WIRING HELP!!!! I'm wiring up an l28 w/ efi that was put in my 73 240z and I need help figuring out what some wires are and where they go. The first is a bundle of 4 wires (thicker red, green, 2 blues. This is the bundle I am holding in the picture. Second, I dont know what this connector is and what plugs into it. It comes out of the wiring bundle right next to where the cpu plugs in (shown in second pic). If anyone can help me figure this out, that would be excellent. I have been battling this wiring for a couple months now. -z_drifter Link to comment Share on other sites More sharing options...

kevo9weber Posted February 27, 2013 Share Posted February 27, 2013 hello ive been reading this post and i really hope someone can help me... from the pictures posted by bumble zee im stuck on the fi relay/plug. the plug that he shows and says you need the b/w, g, and bl/r... he says connect the b/w wire to a switched 12v but when i do i can hear a clicking from the injectors? im so confused... y would this happen. is the b/w wire only supposed to be powered when the key is starting the car or the car is on? or do i have a bad ecu... it simply says switched power... dont really know what the bl/r one does but it not the one im worried about right now... any help would be greatly appreciated!!!

Project1 Posted October 12, 2015 Share Posted October 12, 2015 bumble ... (Yes I know this post is stupid old), Dang! That was a really awesome post. I have a 75 280z with an 83 zx motor. I really learned a ton and so many of my questions about the stock EFI was addressed in your post. Thank you for posting that up with pic!

kerrys914 Posted October 20, 2016 Share Posted October 20, 2016 Can someone confirm the coil wiring? I am doing one final check of my harness....The wiring diagram in the (81 and 82) FSM has the 2 prong connector at the coil ignitor going to the ECCS (yellow) and the other going to ground. The post above states this Black/white wire need to go to a switched 12v (not ground). Just curious as I am not seeing this in the FSM.

kerrys914 Posted October 21, 2016 Share Posted October 21, 2016 Thanks Nismopick... The wiring diagram is not 100% complete. There is another diagram out there which shows the two wires (ECCS & 12v switched power) being conencted. The ground noted in the FSM is actually the chassis ground, not a wired ground as I thought.

Gsax Posted January 2, 2017 Share Posted January 2, 2017 So I'm confused , where does the blue and red wire get connected spliced too ?? Link to comment Share on other sites More sharing options...
Shadow Side Posted March 14, 2017 Share Posted March 14, 2017 If I am only able to source a donor car with an automatic transmission, what all will I need to convert it to a manual? I will be transplanting this into a manual 260Z. I figure the actual transmission and driveshaft are obvious. Are there any electrical or ECU differences, or major gearing differences?
