I have bought a JVC head unit with 3.5" screen so I can fit & use a reversing camera. This needs to connect to the reverse light wire to give power when reverse gear is selected.

- Can anyone suggest the easiest place to connect into the revers light circuit? [my88 S4]

I have looked around the rear lights etc but there is nowhere easy to make a connection.

As a separate issue - the radio signal is very weak / poor. Have tried a couple of head units on most of them cannot receive radio stations - just my old kenwood?

Is there an aerial booster somewhere that may have gone faulty?

Any help would be appreciated.

Thanks
Steve

Just had a more detailed look at my aerial problem -
- Checked the 250mA power out for the aerial & that's all connected
- If I hold the aerial connector I get a better reception
- If I UN-Plug the aerial all together the radio signal is BETTER???

How do you figure that one out?

Hi Steve. Have you located the antenna amp? I think for your MY it's a matchbox sized item below dash. Away from my manuals so can't check location. Better reception unplugged v plugged in is symptom of failed rf amp

Just checked - on LHD car it's 3" x 3" box behind glovebox on RHS, mounted on cabin side of firewall. Should be same place on RHD so have good look under pod

Hi Stratfordshark have you got a L H D car if so were is the ABS ecu mine has the abs light on just bought it .The ecu on my other cars is above the fuse board . on the L H D I cannot find it or the connection loom cheers.

For LHD it's above bonnet release lever on left side

Steve I haven't got a clue on wiring on a 928 but logically thinking out loud here won't there be a connection to the reverse light circuit from bottom of the gear selecter somewhere rather than having to run a wire all the way to rear lights on car?

Hi Chris

Yes, that should be the case - was just hoping to find a reverse signal wire quickly in the boot of the car since all the Rennlist forum listings call out for a Black/Blue wire to tap into at the tool tray - but I can't find the bugger!
