OBC advice please

[TonyF]

I have been reading some of the advice on enabling the OBC and retrofitting the controls. Basically Id be happy with the temp display but the rest would be good. My car is a 2004 986.

My question is this has anyone got experience of doing this with late 986 models? I got the impression from something I read that it was more difficult to do than for earlier models.

I did it on my 2003S, it was a breeze. The only significant issue is that without doing some wiring you will not see anything. You'll need to pop the cluster off, stick the wires in (may as well do all 4) and run them to somewhere accessible. You don't have to add switches or the stalk, for the first three months I just had them coiled behind the colsole. You can operate the OBC by grounding the different wires which is plenty to turn on the temp display.

I currently have two switches in the dash "horseshoe" controlling mine but next week my new stalk set will arrive, then I'll be doing the cruise hack and switching OBC control to the stalk.

One difference from normal, I plan to wire the "down" switch for the OBC through a switch so I can choose if I want to use it for OBC or for muting my radar detector. All features of the OBC can be used without the "down" switch so I wouldn't lose any functionality.
