B.L.Z.BUB Posted January 4, 2012 Report Share Posted January 4, 2012 (edited) OK guys I got my 4age and it seems all the electrical stuff is pretty well done. The only issue I have is I have put my tacho dash in and it doesnt work. I've had a hunt around but most of the threads I'm encountering are to do with after market tacho installs. Can I just run a wire from the (negative side?) of the dizzy to here bypassing the old loom and hope that the ground is still good. If the ground is bad does anyone know what wire in the old loom in that pic is the ground? Electrical, not my strong point. Cheers guys.

Evan G Posted January 4, 2012 Report Share Posted January 4, 2012 yea do that first but with a test wire. don't run it all professional and realise it doesnt work. Quote Link to comment Share on other sites More sharing options...
B.L.Z.BUB Posted January 4, 2012 Author Report Share Posted January 4, 2012 Cool. Will give it a go. Though I'd probably need to run a wire all pro at some stage though. Quote Link to comment Share on other sites More sharing options...

kryton brown Posted January 12, 2012 Report Share Posted January 12, 2012 If that doesn't work, try this. If you look at the link, about 3/4 of way down the page, it lists the 18 pin socket pins. Pin 13 (white wire) is the engine speed signal. Connect this to your Tacho signal input on your dash. Check first that your ECU looks like the one shown.. and just do a test first to see if it will work before wiring it up all pro. http://www.club4ag.com/faq_and_tech_pages/ECU%20Japan%20AE86%204A-GE.htm cheers.

bAKER Posted January 14, 2012 Report Share Posted January 14, 2012 plug into original loom, hook up the wires that went to the 4k coil, to your new coil. should work fine. Quote Link to comment Share on other sites More sharing options...
