Need wiring diagram 99 Dodge Grand Caravan with Infinity Sound System also amp location?

Answer 1

Sorry can't help on the wiring diagram, but thought to offer info on how the Infinity amp is powered in my 1996 Dodge Grand Caravan. After carefully wiring the adapter plug set I got from Walmart so I wouldn't have to cut the wires from the stock Dodge black and grey plugs for my new aftermarket radio I found the Infinity system would not work. My van does not have a power antenna so I taped over and did not use the wires. Turns out that is how the Infinity amp gets it power in my van. In my net search for info on my problem I also found mention that the grounding wire connected to the lug (along with the ground strap) on the back of the stock radio would have to be wired to connect directly to the new radio's black ground wire to get the Infinity system to work. This was not the case for me. I connected both the strap and mentioned stock black wire to the grounding lug on the new radio just like it was on the old. It was connecting the wire on the black plastic plug that is furthest from the little indexing nub to the blue power antenna wire on the plug adapter set that got my Infinity system working. Hope this helps someone!
