need help wiring new tails
i have an 1987 base model firebird and will be changing my original tail lights to 1986 trans am tail lights. what i need to know is what to do about the lights bulbs? what i mean is my car has 6 bulbs for each light but the trans am lights only have 4. do i need to swap the wiring as well or should plug in the ones i need and cut the remaining two? i know other people have done this so help me out here.
o and before anyone says it, i tried searching and found nothing
Thanx in advance

I did this on my Formula wow 7-8 years ago now, anyway you'll need to swap the turn signal socket from your stock taillights to one that will fit the T/A taillights. as for the 2 smaller bulbs, all i did was cut off the sockets and taped off the wires with electrical tape and tucked them into the light harness.
any other questions feel free to PM or E-mail me

Correct me if i'm wrong, but shouldn't you only need to replace the rear wiring harness, like Jproz1167 was alluding to?

yeah i was wondering......do you just have to get the wiring harness from a Trans Am to get the lights to work on a Firebird? I know you have to get alll of it though. Including the hatch motor wiring as it is included into the wiring. BTW, I just checked and the wiring has a connection right behind or by the driver passenger seat. Will it work? Or is it somehow set up differently before this harness wiring?

I just did this last weekend and Dave84Bird's right, it's easier to just wire on the T/A light sockets.
The T/A harness won't "plug & play" because the T/A uses the brake lights as the turn signals and the base model has them seperated.
