HarrisonS Posted April 7, 2017 Share Posted April 7, 2017 So in a spare the moment I thought I would buy a rev gauge to put on my starlet thinking it would be simple and I'm sure it is but I'm quite simple minded so am already confused by the instructions and what's going on. I tried looking down all the tutorials I could find but none of them have the wires I do and I'm not certain where they all need to go. That's a photo of all the wires I have and then it came with some instructions that I find very confusing and I was just wondering if some of you could just shed some light on where the wires need to go and the best place to put themAny help would be much appreciated Quote Link to post Share on other sites
wakeabby14 Posted April 8, 2017 Share Posted April 8, 2017 Its fairly straight forward however you will need to purchase more wire as those will not reach for what you need to do. Both reds to 12v source probs best linking to cd player/stereo system in the front to its positive as it is on all the time when ignition is on.Both blacks to bolt under the dash/body for the earthand the green to the -negative coil side in the engine bay or at the back of the ECU if you want to do that. If you are not very good with that stuff ask a friend or someone to help and disconnect the battery also to prevent any accidents. Here is an ECU wiring diagram to try and help. http://www.toyotagtturbo.com/forums/showthread.php?20491-EP82-EP91-ECU-Pinout-Diagram Quote Link to post Share on other sites

t'mill Posted April 10, 2017 Share Posted April 10, 2017 Keep us updated with progress pal if you could (preferably with photos) as I fancy a rev counter too. Quote Link to post Share on other sites

t'mill Posted April 17, 2017 Share Posted April 17, 2017 Can anyone point me to where the ignition coil is located please? I've had a good shufty in the engine bay but can't see it. Quote Link to post Share on other sites
