Hey has anyone bought the harness off the most wanted parts section?? If so is that what the price is with the harness or do you have to buy the bulbs seperatly?? or does it come as one?

Is there a big upgrade over the stock headlights with it?

Stock the current for the lights runs throught the switch. this created problems for 89-93s. The harness was a solution. 94-97s generally do not have this problem, but the current does still go through the switch.

The difference in your application would be minimal. The bulbs would get abit more voltage (as there is no longer a voltage drop across the switch) but it wouldn't be night and day.

when i added the competition limited harness to my car it made a big difference. my lights seemed much much brighter. i didnt change the bulbs either, just added the harness and it was noticeable. i got mine off ebay last year, didnt come with bulbs though, just the harness. worth the money in my opinion.

I wish I had pics of before and after on my 89... the difference was practically night and day. :uppoint: I did put in over wattage bulbs in, but on 89-93s, the harness makes your brights light up all 4 bulbs. Before I could drive around with my brights on, and never get flashed by other drivers. After, i got flashed all the time with just the lows on!

I'm not surprized Frank saw a difference, here is why:

Watts = Volts x Current
Watts / Volts = current

So, you take a normal 65w bulb. We assume it gets it's rated 12V. so, 65w / 12v = 5.4 amps. now, Voltage / current = resistence. This gives us 2.22 ohms.

Now lets assume your wiring has degraded some, and there is a drop over the switch. You bulbs are only getting 11v. Volts / resistence = current; 11v/ 2.22 ohms = 4.95 amps. current x volts = watts; 11v x 4.95 amps = 54.45 watts, or a loss of 16%!

A good way to tell would be to start up the car, and measure the voltage across the battery. then take out one of the bulbs, and measure the voltage across the connector (with the lights set to on).

just wonder can i still use the stock 65/55 wattage bulb instead of the higher wattage one because i like my silvestar with the harness?

will it burn out the stock wattage bulb? i didn't see the reason to burn out.
