96-98 tails

The harness that my 96-98 export tails came with had a different plug than the 94-95 body harness. I ended up using some tap connectors to attach them, rather than hack up the wiring. I'm not sure if this will apply in your case, or if it's strictly an export tail thing.

It's just an export tails thing, the 96-98 harness plugs right in. You can even use your 94-95 harness, but one of the bulb sockets won't fit. On my 95 GT, it originally had 96-98 tails on it but still had the 94-95 harness. One of the bulbs was hot-glued in place, but it leaked and ruined the chrome in the tails.

Matt, I did find a place some time ago that had the export harness socket that fits the plug in the export tails harness. They weren't cheap, like $20 for the pair or something similar, but would provide a clean installation. If you're interested, PM me and I'll try to dig up the info.
