LHD W.G (West Germany) wires from dimmer & dash switch to headlight relays?

[Bean]

do you have access to the actual diagrams? else get it here http://www.aeu86.org/technical/ae86-manuals/ the 1983 one and check page 28 and 29 (also read page 4 and 5 carefully so you understand the lingo on the other pages and where to look).

In my opinion the best way is to go methodically. Check that all fuses are fine (should be 5 in total). Also check that all light bulbs are working - both high and low beam.

If I read right in your other topic your highbeam light on dash is not working either? also be sure that the bulb is fine. If I counted right there's also 15 connectors to check for continuity and proper connection. These connectors should also help out with diagnosing the whole issue.

Am I right that you did an engine swap? did you double check that the relay board is connected properly to the rest of the system, one unlucky wire is all it takes sometimes.

Last but not least can you try and condense the current situation as factual as possible?
I.e. what happens every step of the way and how it's connected right now etc...

PS: to check if you got high or low beam just hold a piece of paper some 30cm in front of the light, you should be able to see the anti-glare pattern on low beam.
