Ok, I have 2000 Toyota 4runner and picked up a new Pioneer CD player (single DIN) from Crutchfield. So I go ahead and wire up the harness that came with the radio (the single harness for the back of the new stero and the two adaptor harness that were supplied with the install kit) ad yes I read the direction.
Went ahead and pulled the stero apart tonight and to my surpise I have one single harness plugged into the back of the OEM deck (cd and cassette deck). The harness is slightly larger than the largest of the supplied harness.
With a stumped look on face and some confusion I put it all back together and came to this point. Now I have a few questions -
1. Should there be two wiring harness hooked into the factory deck?
2. Why would the factory harness be larger than the supplied harness?
3. Where could I find a larger single harness adaptor?
4. I have to idea what I'm doing and should jus bang my head into a wall. (just kidding)
Hopefully, this makes since.
