Small brown plug

Hi!

Whilst repairing my head light switch "pack" I noticed there is some sort of control unit behind it. There are 2 small (5 pin?) brown plugs, and one of them seems to be unplugged. Any ideas what it does? everything seems to work as normal.

My ZJ is a RHD model as well.





I'd appreciate any advice. I couldn't find out what it was after searching last night. I don't want to simply plug it in and bugger something up, the electrics have not been kind to me - highly unusual from what I can gather!

Judging by the other plugs on it, that looks similar to the US-Spec Body control module (BCM) which does not have those two extra brown plugs.

Ahh It makes all the right noises to be a BCM. I'm just stumped as to what these 2 plugs are for. Things which are unplugged annoy me unless I know the reason!

At least I know what to look for now!

eBay for a printed one, lots of online retailers for an electronic version with immediate download. Or, if you look hard enough, you may find the PDF version for free. That said, you ideally need the RHD version (aka the Jeep ZG), which probably isn't as widely available, at least not for free.

You're probably best off asking on one of the UK Jeep forums, like Birty Dastard's.

I've found a 1997 ZG FSM just browsing through it now.
