finmac Posted November 16, 2017 Share Posted November 16, 2017 So in the process of wiring a set of Aces shift lights to my SLR and wanted to check which wires to connect to please?theres a black which I guess is Earth?greenred/whiteblack/white thanks Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted November 17, 2017 Leadership Team Share Posted November 17, 2017 IIRC ...There's red and black cables for power, red is the ignition switched +ve, black is earth.There should be a black shielded wire with a pre-installed spade connector, this goes to the low tension side of the coil or the lead that then runs to the tacho, I think it's black/white.Plus there's the loom lead that connects the display to the control unit.I don't recall there being the other wires you mention, although if it's a s/h unit it may have had the wires added or extended? Green is usually an ignition switched live, Red/white is usually the gauge illumination circuit.Stu. Link to comment Share on other sites More sharing options...
finmac Posted November 17, 2017 Author Share Posted November 17, 2017 Morning StuThanks for the reply, just realised I worded my question very badly!The wires I was referring to are the ones on my Rev counter and I was trying to work out which ones to splice into.So in summary on the tacho Black = earthGreen = switched liveblack and white = tacho signalcheers Finlay Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted November 17, 2017 Member Share Posted November 17, 2017 Sounds right, but is the third white with a black trace or black with a white trace?MOCA2CV's excellent notes and pictures for a DRE unit.

Member Jonathan Kay Posted January 27, 2018 Member Share Posted January 27, 2018 OK... what wires have you got from the car, and what from the shift lights unit?Jonathan Link to comment Share on other sites More sharing options...
finmac Posted January 27, 2018 Author Share Posted January 27, 2018 So from memory green on tacho connected to red on ACESblack on tachometer to Black earth on ACES Shielded wire is the one I'm unsure about: it doesn't have the pre fitted spade connector. So it's a bare wire with shielded inner and outer core. How to connect to the tacho feed? Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted January 27, 2018 Leadership Team Share Posted January 27, 2018 Fin, probably worth taking the ignition switched positive (red) and negative (black) feeds for the ACES unit independent of the tacho, Without the shielded cable connected the display should light up momentarily when the ignition is turned on, if it does then that side of the wiring is correct. The shielded cable can then be connected to the white/black coil to tacho cable.Stu. Link to comment Share on other sites More sharing options...
finmac Posted January 28, 2018 Author Share Posted January 28, 2018 Thanks StuMight be a daft question but how to connect the shielded wire to the tacho wire?i take it the inner wire needs to be connected to the tacho wire and if so what to do with the outer shielded wire?
