Circuit Diagram for LIR Tpye L1 Relay in 401/403
The 401/403 has a lockout in the electrical system so the High Beam and Fog Lights cannot be on together I believe. This is done using the LUCAS LIR Type L1 Relay mounted up behind the dash. It takes input from the Fog Light Switch and sends it off to actuate the Fog Lights. There is also input from the high Beam Warning Light which serves to cancel the Fog Lights when High Beam is selected. At least that is what I work out from various circuit diagrams. The Relay also has an Earth input. I am doing a rewire using a Vintage Wiring Harness Loom. I cannot figure out the actual layout of the 4 wires to the 4 screw in tabs on the Relay. I can get the switch to throw but not turn the lights on. Any Ideas of what goes to what.
