higher wattage bulbs

Do you think the stock wiring harness could live with 65/70 watt bulbs?

I wouldn't chance it. It has enough trouble with stock bulbs sometimes, particularly the switch. Throw a relay in there.

x2! Besides, if you do it right, you get the added benefit of MORE light output, since the bulbs actually get more voltage..

When I installed relays and higher wattage bulbs, I measured voltage loss from the battery to the lights.

Stock lights, 55/60 Amp, stock wiring, 13% voltage loss low beam and 18% high beam. Thats 1.6 and 2.2 volt loss....

Stock lights, 55/60 Amp, upgraded wiring and relays, 2% and 2%.

Hella ecodes, 80/100 Amp, upgraded wiring and relays, 3% and 4%.

I ran PIAA super whites without problem using the stock switch. But I agree with everyone that you should run a seperate harness. I went on ebay and purchased and H4 wiring harness for about $27.00 and installed it. Easy to do as I ran the power wire off of the starter motor. Now it is only stock current or less running through the original harness just to activate the 2 relays for the lights. I can email you pics or walk you through the install of the H4 harness.
