So I've got a DX sedan. I've raided a junkyard for power mirrors, cruise control and various other things. Cruise control being my main concern as I'm on the highway everyday for about 45 minutes.

For a long time now I've been going over wiring charts and crap to manually wire all this in, but then when I was outside working on my LX it occured to me that I should be able to just use the entire LX harness and be good to go. So much easier!! Afterall, they do use the same DPFI crap.

I was hoping to be able to get away with just using the interior harness, but then I realized that the CC crap goes all the way out. So I'd need the engine harness too, unless I cut just the CC stuff out at the junkyard.

I'd also prefer to get the entire floor harness so it'll be easy to swap in the power window, lock and mirror crap.

So basically, I'm thinking I need EVERY harness from the LX.

It'll be a PITA to pull and swap it all, but that way I know it'll be completely OEM and I won't have to worry about wiring screw ups etc.

Can you think of any reason why I would not need to pull the engine, floor, and dash harnesses?
