Question
I have a Jensen model CD310X CD/radio with no female plug to fit the 20 pin jack at left rear of unit.

Where may I obtain a pin out wiring plan to safely make these connections?

Thankyou

Answer
Ben,

 ok i think you have made the first big mistake which is clipping the stock harness plug from your dash and trying to wire in straight to your new unit... first i will tell you what you should have done then i will give you a cure .. you should havbe purchased a wire harness adapter *8-12* bucks this will wire into your new unit color for color then plug right into your factory plug so every thing matches up .. if you can wire the old plug back on and do this .. but in most cases you cant .. so here is a site that might help you out www.streetdreams.com/wires/
hope this helps you out if you need anything else let me know

thanks
