Headlight Wiring Harness, is this good enough?

[David]

I have a 1987 Audi COupe GT with Euro headlights (typ85 80 lights). Right now I am running with the stock wiring and 60/55w H4 bulbs. I want to run 100/80 watt bulbs and use a relayed wiring harness to lower voltage drop and lessen the chances of melting anyting. So, given that I want to run 100/80w H4s, are these pecs good enough?

"New & Improved Wire Harness features:

* 2 OEM Bosch/Tyco (Potter & Brumfield) 40 amp relays (single & dual 87 outputs)
* Heavy Duty interlocking relay sockets with mounting tab
* Fusible link (slow reacting fuse protection) 12 heavy gauge automotive wiring
* Black split loom matches OEM to protect against heat and elements
* Male connector(s) to plug into existing headlight socket
* (2 or 4) new headlight sockets (depending on application)

The Heavy Duty models are 14 gauge wire.

They also offer a H4 Super Heavy Duty model is 12 gauge and uses 4 relays. But it's quite a bit more expensive and if I don't need it, I will just get the Heavy Duty one...

Also, they offer a mod to their harnesses that allow you to keep your low beam on when you turn on the high beam. Good idea or bad? If I got it and was running the 100/80w bulbs, that wwould be 180w combined per bulb. Down sides? Too much heat? Too much current draw?

TIA!
