Phaz

I removed my aftermarket steering wheel, to replace it with a better one. I noticed that there was a gray plastic circle with two pins sticking out you can push it in and it springs back.

ive just try'd to put the radio on and nothing no power to anything, put the wheel back on still nothing, battery circuit breaker was off whilst i removed wheel nothing has blown.

Have i trigged a saftey device or something? FD's a 1997 type R

ive pulled apart my car all fuses ok main fuse ok, gone through the usual with electrical tester . When i put the battery on the interor light goes on for about 2 seconds then nothing, no key alarm when key inserted really weird

any ideas
