Hi

My Rover Mini Mayfair 1993 has a factory fitted Maystar MCA 660 radio as standard. I've checked the wiring and have discovered that my radio has permanent live and no ISO connection. There are a whole bunch of coloured wires; some are connected via a block and others have ends taped up. I'm guessing I need to 'make' an ISO connection so that I can connect to the wiring harness which has been supplied with my radio.

Any advice you can offer would be helpful.

Cheers

you can buy the iso leads from ebay/hellfruads/motorworld etc.

They come with the iso and bare wires at the other end to connect up to the car

Or you can just cut the wires off the stereo's harness and join them to the cars wiring.

Hi

Thanks for this.

Should I try and crimp the bare wires to fit into an ISO connector and then connect this to the harness supplied with the HU?

personally, on all older cars I've worked on, I usually just use crimp connectors, female on the car's wiring, and I then cut the iso block off the stereo wiring and connect it up. The stereo should come with a wiring diagram to tell what wire does what. Make sure you use the fully insulated femal connectors though, as it saves having to wrap each connection in tape lol

I tend to put bullet connectors on the power/etc feeds and then blades on the speakers. Makes the wiring easier to work out at a glance.

Make sure you get the polarity right on the speakers, as they will lose all bass response if you wire them out of phase, (i.e one properly and one backwards. Had a cinquecento that had had rears put in. took me ages to work out why the 6x9's had no bass at all. lol)
