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?

Took a closer look at the panel. I don't have an owner's manual, so I'm a little unsure of what fuse does what, and what size it's supposed to be. The cover plate has an icon of fog lights on the 3rd fuse from the right, but my melted fuse was the 4th one over. Weird. I think the PO wired things up wrong. There is a inline fuse going to the switch too, definitely not Porsche stuff. If anyone has a fuse box diagram for a '71 I'd love to see it. Looks like I've got some sorting to do to get this right.
