Installing new head unit in 98 2.3CL before I cut harness jack need to identify wiring. Like the remote controls on steering wheel etc. so will function with new unit. Changing new head unit, door speakers, rear deck speakers, adding amp. & sub woofer box. New unit is JVC has no jack just bundel of wires.

 

pushing the search link would help.

 

you can buy a connector that connects the factory plug to the aftermarket headunit. i just did this the other day

 

Yea you can go to a best buy or your local radio shop and they should have the adapter all u need is you car model and the radio brand..... its the easiest way to do it
