Hud Harness and Connector Question
This week, I picked up a cluster for my 98 C5 so I can install a hud. Everywhere I read, people say the harness is an 11 pin cable. Yet, everywhere I look at pics, the connector for the projector is 10 pins. The one on my cluster I just bought is 10 pins. (bit difficult to put an 11 pin idc connector in there).
Am I missing something? (Yea I know, besides a pin?)
Also, does anyone know where I can get the new cluster reprogrammed for the odometer and ECM, inexpensively?

No it doesn't. It just has the basic cluster with two open wiring harnesses sticking out each side.
Ah, now that I look closer, that harness on the left you are talking about comes out as just a 6 pin IDC connector. But, at the other end, there's an 11 pin header on which to plug it in. So, I need to add 5 more pins to that end? Then the top header connector which actually goes to the projector, that's 10 pins. I think I get it now.
So, projector is 10 pins, control connector is 11. Need harnesses for both, or for one and retrofit the other?
Just didn't want to spend the next $500 without a good idea what I'm going to end up with. Thanks.
H&R Radio Svc in Warminster PA will do the reprogramming job for $125+shipping. Anyone know of a less expensive place to do that?

What I mean by retrofit the harness is, add the extra wires it needs. Right now, it has an 11 pin idc connector with just 6 used holes. I have the pins for that type of connector (do rather a lot of electronics work). I can just add the other 5 wires. Then at the other end, it has just the 6 pin connector, I'd just cut that off and replace with an 11 pin so it would fit that HUD/Dimmer control that you are correct, I do not have yet. That comes with the projector kit from GMPartsHouse. I also am trying to buy a more complete cluster from the for sale section, so if that goes through, I'll save even a little more work.

Good luck.
