Jessopia74 Posted May 25, 2022 Share Posted May 25, 2022 Are you wanting to go with a separate relay installation? Quote Link to comment Share on other sites More sharing options...
Sutty2006 Posted May 25, 2022 Share Posted May 25, 2022 If I remember correctly, there isn’t one. They were wired up by dealers before being sold on the forecourt. My first E plate GT exclusive 1.8 twins were scotch locked in. I’ve wired my current twins up on a separate relay. Fairly easy to do.

IanG Posted July 8, 2022 Share Posted July 8, 2022 If I add twins to the Cav I will fit relays, assume I will need one for each side? How do I wire these in, can anyone explain please, and what rating relays would you use? 1 Quote Link to comment Share on other sites More sharing options...
2400man Posted August 17, 2022 Share Posted August 17, 2022 (edited) Interesting to read that there were no official wiring diagrams for the twin headlights. To compare and contrast, I used to have a Taifun aftermarket twin headlight conversion fitted to my hatch, which was different in the way the lights worked, compared to the oe Irmscher lights and I actually prefered the way the Taifuns operated. I also converted them to a full relay setup. Irmscher lights - outer dip/main beam H4 bulbs and centre spots running H1 bulbs. On dip - outers on only in dip mode On main - outers switch to high beam and centre spots come on. This is great for having loads of light shining up ahead but there's less in the foreground In contrast, with the Taifun conversion, all four lamps were running H1 bulbs On dip - outers on only (on dip obviously) On main - outers stay on and centre spots come on with the result that you get plenty of light in the foreground as well as up ahead. The same system is used on my Saab 9000's I don't know if anyone else has tried this but at some point, when the car has an engine etc 😁, I'm going to design a wiring set up with relays for the Irmscher lights on the coupe which copies what the Taifun lights did - basically the high beam on the H4 lights will be non functioning and the low beam filaments will stay on when the spots come on when switching to main beam.

I could probably advise on relays etc. Edited August 17, 2022 by 2400man Quote Link to comment Share on other sites More sharing options...

I could probably advise on relays etc. All sorted thanks managed to buy a wiring harness made up to take std H4 plugs and then splits into two loops both with relays built in each side into H4 connectors, all I will need to do is add a feed for the H1 spots. https://www.ebay.co.uk/itm/394081005516?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=JoSkOPTTSgG&sssrc=2349624&ssuid=1oAQMJSaQsq&var=&widget_ver=artemis&media=COPY 1 Quote Link to comment Share on other sites More sharing options...

H4 plus H1 is slightly easier to setup with relays than H1 plus H1 as I recall. 1 Quote Link to comment Share on other sites More sharing options...
