Oh come on Brian..., you know what you're missing

Madmonkey, eat a snickers.

Because you turn into a location dictator when you're hungry.

Better? Better.

So what else is needed for that HUD? Just the trim piece?

As far as I know, that is correct. I believe it's 40 for that trim piece from rock auto.

Hmm..does it have the harness to just plug it in or does everything need to be spliced?

You may already have the harness. There's a write up on gpona for it. I was going to install this on my car but never got around to it, so I can not confirm exactly what it will need to work.

Alright I hear ya. Im looking to see for the trim now..and I understand I have the harness already..but the hud unit you have has the other side to just plug into that was what I meant?

The trim piece is GM P/N: 10354107

The harness I have is cut incase it needs to be spliced in to a car that has no harness. I've heard some people have everything to where the HUD will be plug n play and others won't have it.

I'm sorry if my responses aren't the greatest. I wanted to install this but demodded my car before I had a chance.

No youre good man, I just needed to specify more. Okay so since its spliced..do yiu have the connection piece or since its like that, id have to splice it into mine for sure.

I have a bit of wire and the wiring connection that plugs into the HUD itself. I don't have any wiring for the switch because I already knew my car had that.

Pmed ya

Brian's a good guy, he had the info here in the 04+ section.


ok, back on track no more take over posts.

How exactly does the alt relocation work? I'll be ic in a few months and was wondering if that's something I'll be needing.

98-08 4T65 HD differential upgrade- new/used? If new, still have the bearing? Miles if used? By output, do you mean axle? Please more info. Very interested. Thanks

A little extra clearance never hurts. All the info I can confirm is on ZZPs site. http://shop.zzperformance.com/store/...-Brackets.aspx

No instructions came with it, but it looks like it just bolts up to the factory location and the alternator bolts up to it.

Sorry for not posting more details initially. It is used. Came off a car that had 60k miles. Im not positive which bearing you are asking about, but here is a picture of what is included. Since this picture was taken, the housing has been cleaned up some.
