BushidoB 0 Posted May 27 Hello I've recently taking an interest in car wiring, after years of blindly letting someone else do it. I'm learning a lot, but have a random question, more out of curiosity. I've attached the diagrams from the starter system loom (I'm keeping in mind this is for the GT RHD). I've attached a pic of my set up (I never originally wired the car - mk3 71). The wiring diagram has a 3rd red wire with yellow wire. I don't have these. What would these typically be for? It reads as through they're also going back to the ignition switch. In this set up, is the red feeding anchoring off the relay to feed ignition switch power? Not sure what the Yellow is for.

sheffieldcortinacentre 600 Posted May 27 The 71 cars have some oddities , changed with the minor facelift for early built cars. The red is probably the charge wire from the alternator this normally goes to the battery end of the large lead via a fuseable link wire. I think the yellow is ammeter wire ( on a GT/GXL) if memory serves. The manual/parts book tend to show the first diagram, there would've been a service bulletin with an updated wiring diagram etc. The ohc cars went to a pre engaged starter motor. The ohv retaining the inertia one with separate solonoid unless yours is one of the extremely rare 1,6 ohv GT/GXL versions made due to problems with the 1.6 GT ohc engine.

BushidoB 0 Posted May 27 Ah, got it. Yeah, mine's 1600 OHV with inertia motor. Thanks for that! Quote Share this post Link to post Share on other sites
sheffieldcortinacentre 600 Posted May 27 That's a rare car I've only seen one at cortina day a few years ago I think. Yours will have the clock on left & tach on right if it's an early one too. Ah your a bit far to help in person. Always happy to help if I can. Quote Share this post Link to post Share on other sites
