Well, I ran all the wires for the brain and head unit, but now I have some questions. (been many years since I messed with this stuff)

First, I need to locate the speed sensor wire and reverse wire colors in the harness. I tried searching but no lock on here so far.

Second, I guess I need the adapter so I can splice the new unit into the factory harness. anything specific here or pick one up from dealer or best buy?

Third, I have the bazooka sub (for now), and I'm trying to figure out that as well. It is amped, but in order to use the new HU sub out, I need to use the sub out line (RCA) on the new unit, but how do I get this to the factory sub wiring.

ANy help would be appreciated

 

I found the info for question 1 and 2....Question 3 I guess I will just play with.

 

If you have the factory Bazooka, and you use the factory wiring harness connector, then the sub will still plug in between the head unit and car wiring just like stock. If you wanted to use the sub outs on the head unit, then yes, you would have to do some modifying.
