Volks, here is a better description of what I am trying to do. Credit goes to TJ Hannick Time used a Bosch 30 amp relay. I use a 40 amp because I happened to have one. Removethe connector from the terminal 57 on the back of the light switch. This connectror has two wires crimped in it - large white wire and a smaller white wire with black stripe. Plug this connector into the output pin (pin 30) on the relay. Make three jumpers as follows: Two (2) 4" jumpers of 18 gauge wire - .250' female connectors each end. #1 jumper - plug one end into pin 57 on the headlight switch - the other end into the control terminal pin 85 on the relay.. #2 jumper - plug one end onto multiple ground connector behind the fuse block, and the other end plugs into the relay ground terminal - pin 86. One (1) 18" or so jumper of 12 gauge wire with a .250" female connector on one end and a .250 insulated female connector on the other end. Plug the unshielded connector into the supply of the relay - pin 87. Plug the insulated connector into one of the "P" terminals on the fuse block. Using double stick tape, mount the relay just forward of the light switch on the fascia next to the instrument pod sufficiently far over to the side so as to clear the instrument pod cover. Notes: VW uses female locking tab connectors. You need to have something to release those tabs. I found that a jewelers screwdriver does nicely. Everyone has a set in their toolbox - right? Relay socket vs just the relay. - If you use the relay socket - the VW connectors will snap right into it. I prefer the relay socket and made up my jumpers using the VW type connector on my jumpers. Makes changing the relay a snap. If you use use the relay alone - then you will need to use the insulated connectors. The wiring path is stock from the relay to the headlights. A measured 0.1 volt drop between the output side of the relay and the low beam fuses (24 & 25), so the dimmer switch was left in the main current path. Total cost thus far - relay, socket and locking spade terminals(connectors) - about $6 bucks. A high beam relay instalation was planned, but since the high beam current path doesn't go through the headlight switch, it really isn't necessary. Final note - With Hella Driving lights - the fused relay for them was placed next to the headlight relay. The headlight switch output controls the lights so they will turn off with the headlights when the ignition is switched of. A three position VW fog light switch is wired to also allow independent operation of the driving lights and is placed in the blocked out opening above the rear window defrost switch. Please credit the above description to TJ Hannink. ****************************************** My comments - The installation went well until I discovered there were no unoccupied "P" terminal available. I just need to find another place to plug in. Although I don't know the actual routes of all the added wiring installed by the PO - everything in the van works - so all those wires have an active function. They are not just dead wires. It's just that they run al l over everywhere and there are no "as-builts" as it would be expressed after a construction project. So - I'm open to all suggestions. Right now I just need to know of an alternative place to put that one wire so it will do what was intended. I'm sort of desparate for my headlights and looking for the quick and easy solution at this point. Thanks John
