Default 84 Headlights...upgrade to 88 Module...need wiring help!

Hi all,

I know some of you have done this, so wanted to know if you know what I need to do to connect the 88 style Headlight control box (driver fender) up in place of the 84 style headlight relays. My 84 relays are bad...and I have an 88 module here...want to get it fixed tonight...

PLEASE HELP@!

you have to upgrade the headlight motors to the 88-96 style. $$$

It's not just as simple as wiring the module in, in place of the relays. The motors have to be taken apart and some internal wire swapping/soldering done. I made this mod on my '85 because the limit switches in both motors were shot and this was cheaper than rebuilt motors. I found the instructions in an old post here. After a bit of grief they worked. If I had it to do over, I'd bite the bullet and buy rebuilt motors. If all you need are the relays, I don't believe they're too expensive and all you have to do is plug 'em in.
