NA Dash Harness in a TT

[GRSHOPR]

I can't remember off the top of my head- can I use a 94 NA dash harness in my 94 VR4? I'm restoring and painting a new dash to put in my car, but I can't remember if there are any differences between the harnesses, and if it's safe to use the NA one or if I HAVE to use a TT one. Thanks!

One difference I can think of is NA has a volt gauge where TT has a boost gauge.

I'm going to replace the gauges with Defi instruments. Thanks Brian! Maybe it's just best to swap over the harnesses?

Does that harness control the stuff in the console? That stuff would be different than the base harness, also I think there is some buttons around the main cluster bezel that are different.

If you have the harness I'd probably just swap it out.

If you're going to aftermarket gauges, it doesn't matter. Only wires you may be tapping off of for the gauges would be power and ground, you'd run new wires for the senders.

So long as your TT and NA dashes have the same options, shouldn't matter. Otherwise if you have to wire in like a digital CC or similar, that'd be about the only differences that I'm aware of.

How about ECS (if not on the NA dash already) and active exhaust?

One of the differences I was talking about on the base bezel. The SL harness would be closer to the TT harness than the base model.

Thinking about it, I wouldn't be shocked if NA's without ECS still have the harness for it in the dash. I haven't really researched that though since I don't care about ECS.

I know the cars that came sans fog light have the harness already there. All I did was buy a set of fogs and take the dummy switch out and installed a factory fog switch and it works like stock.

I don't remember the plug being there on mine but that doesn't mean it's not there (ECS).

Unsure. I'd have to check ASA and see if there's different part numbers based on years.
