Need some help wiring up a relay to some fogs Options

[Jameel]

Finally getting the front end of my '71 looking finished. I mounted up these Cibie and Hella lights and got them wired up today. All went well during testing, but on a drive I blew a fuse, then outright melted another one. Came home to rethink.

I have wired up the J West H4 relays on several 911's, but I have not done it on a 914. I had assumed when wiring this that the round relay in the fuse panel under the dash would be sufficient. It's not apparently!! So, couple questions.

1. I'm running four 55W halogen bulbs, and that works out to 4.58 amps per bulbs, so less than 20 amps total. The Hella bulbs came with a 30 amp relay. Is that relay beefy enough to handle the four 55W bulbs at 20A?

2. If I do wire up this relay, where do I put it? How do I handle the round relay in the fuse panel under the dash?

3. If I switch out all the bulbs for LED's, will the round fuse be all I need?

Relay it near your fog lights you leave the existing wire/relay alone, it plugs into the new Bosch relay and it's now just a switch with no big load. You run a heavier wire to the new relay, that's now the power for the lights. I'd mount it near the lights, make an extension wire to run from one of the the old fog light +wire to trigger the new relay, You can do this without cutting any of the stock wires.

Thanks Mark. Sounds like I'm going to have to run a new wire up the tunnel to the relay. Ugh. This is so easy on the 911 because the battery is right there. Is there a way to do this using the existing harness?
