does anyone know what type and amperage relays i need to build a wiring harness for my '91?

 

A wiring harness for what?

If it is for high wattage headlighs, 2 x 100 watt = 200 watt or 16-some-odd amps. Most relays will handle 20A, many will do more. For switching "on" functionality, you will want a relay with "NO" or "normally open" contacts. You can get them in electronics stores for around a buck on sale, 2-3 dollars normal price. The pre-wired sockets can be had for about a buck too, but you will find the leads are not very heavy duty. Better to solder (or crimp if you must) some spade connectors onto your wires and slide them onto the relays. Most automotive relays have a mounting bracket that makes it easy to affix to a body panel somewhere.

Good luck,
John

 

Thank you for that information John. I should have no problems doing this mod after all. It is for my PIAA Superwhites 45/65. I learned a lesson about higher wattage bulbs. I am getting new headlight housings for my '91 here directly. The reflective coating inside my current housings is deteriorating. I also thought I owed it to myself to beef up the headlight wiring considering they're 11 yrs. old and puny to begin with. So I hope that by upgrading the wiring and installing new housings I will get more light on the road. I find it difficult to get help from people on the org. Again, thanks.
