Hi/Lo Headlight Relay, 4prong vs 5 prong? Options

[jPs]

Hi All,

I picked up a 914 a week ago and am trying to iron out a few bugs before I get it back on the road and have reached a point where I sure could use a little advise. So here it is: The headlights won't switch between hi/low and in trying to figure this out I took the steering wheel off to check the turn/hi/low switch. It looked good and so after cleaning it all up I still didn't have much luck. So I then took the relay out (on the fuse panel) and noted it looked new. The PO I got this from had given me some extra parts and I noticed the old relay mixed in with them. The difference between the two is the new one is 5 prong, the old is 4 prong. I put the old one in and it would switch between hi/lo but not all the time.

So, I called the porsche dealership and the manager was very helpful and suggested I contact the guys over at the VW side of the dealership and have them order the new relay as it would be cheaper. I picked it up today and it was the same 5 prong I already had. In short, I went back to porsche and ordered what will hopefully be a 4 prong but the guy said the parts sheet didn't show if it was 4 or 5 but we'd find out. So I guess my question is will the 5 prong work and if so anyone know how? The schematics look close but I don't do electronics very well and basically am clueless. One thing I know for sure is if I can get the new 5 prong working I could save some cash for other items I need.

Any advise is appreciated. Thanks!
