Wll i got this for fathers Day and my son and I installed it today in the 91 Sonoma.
Pic of the wiring install. This was very easy and simple to do.
Couple of installed Pics.
Bought the unit from Crutchfields. $150 for everything including shipping. I had a $50 AMX gift card for test driving a Lincoln Zephyr so the cost was only $100.00.
Sounds way better that the stock unit and I can now play CD'* for my son when we take the truck out to run errands.
