What I don't hear is the compatibility of the cable connections. For example, If pin one in the radio is audio left channel then pin one in the changer must be the same. I am still trying to find out if radio and player manufactures provided cable specific to each model or they agreed on universal set up.

 

Refer to electrical guide - free download.

See below, too:

1993 xjs

 

With an xjs you're in the wrong forum entirely and the systems are utterly different.

 

Sorry about the wrong forum. On the xjs the output/input from the cassette radio is a 5-6 pin DIN plug. I was trying to determine what the function of each pin was by analyzing the input/output of the radio. Once knowing thsi I could know if I could modify any changer to function with the Jag radio

 

Maybe the XJS electrical guide shows?

 

Well, it is all overcome by events! A CD player pop up on Ebay and I bought it forthwith.
Thanks for your comments and help

I know we don't have the same cars, but I can't find the cable in the XJS. Perhaps it is in the same location as your car. Quoting you:

"I did find the 12 pin plug buried in a harness in tape at left rear."

Could you be more detailed: Driver side/Passenger side LHD RHD???? Left Rear: Would you detail Rear, please
Thanks for any help....anybody!!!
