Scroll down to 2.5.4, it shows the splicing.
I just put a Kenwood deck in mine and went to Radio Shack and bought some of the round pins, then attached those to my radio output wires. Then found the appropriate wires in the SVX connector and pushed the pins in.
The pins are not the perfect match in size, so you have to push them in quite hard. But they wont fall out
I believe SVXdc also has the connectors for the swap also, check with him.
