Im getting ready to drop my RB into my vert and i was just going to use the harness of my base model hatch b/c its already converted.So far everythig is pretty much the same,except this white plug under the dash.I know there is the brown plug the hooks up were the glove box ist thats the only one i had to hook up the last time.The RB harness dosent have this white plug,so my question is do i need it?It sure was a pain in the butt to get to also.

It's been a while since I've studied RB wiring... lol. Isn't that the dash harness... tach, speedo, etc.. ?

I'll take a picture of mine if you need it. But I bet someone here will answer your question before I do.

btw.. I moved this to the RB forum.. you'll get better help. There are few RB owners in the 'vert forum.

Thanks for moving it to the RB forum,for some reason i didnt even think to post it here.

I had to move the air condition box from under the dash to get it.When i unplugged it,it looked like it went outside under the fender to the fuse box,but its hard to see when your laying upside down on your head,so im not totally for sure.lol

I thought the brown plug is what control the dash and such?Thats all i had hooked up on my hatch.

Lee,you are correct. The light brown connector goes to the instrument cluster in the dash.
