My '75 has period correct fog lamps and dash pull switch with terminals 31,15 and K, but the wiring looks suspicious . looking for a simple diagram showing where each of those 3 terminals should be connected, Thanks, Jeff

QUOTE(Spoke @ Nov 6 2025, 05:18 PM)  Here's a simplified view of the foglight wiring. The diagram that you sent has the same wire color connections as my round fog lamp relay mounted to the far left of the fuse panel, however my fog lamp switch has two wires that were attached. A green connected to terminal 31 mounted to chassis ground and a yellow wire connected to terminal K and then through the front bulkhead to a small 1"square relay mounted to the inner fender just left of the break fluid reservoir. I can't find any info on this small relay. 5 terminals numbered 87,86,30,and two 87 terminals. Does any of this sound familiar? Thanks, Jeff |
