AXTOY28SWC - SWC add-on harness w/RCA for Toyota with 28 pin connector
When installing an aftermarket radio the AX-TOY28SWC will allow the user to retain their factory installed steering wheel controls without having to splice into factory wiring (ASWC required and sold separately).
In addition we included RCAs to allow the user to retain their factory installed 3.5mm jack. Aftermarket radio must have Aux in. This is an optional harness. Main power harness is still required.
