Retrofitting webasto t91 remote controller

[Jim Cummings]

Hi Guys,

I have a VW t5 2009 2.5 4mo. I have the original webasto thermo top c installed (which works:-) and the previous owner has had the aftermarket webasto 1533 timer/controller installed. I wish to add the t91 remote control which I bought on eBay. Has anyone installed this in a t5 with air con, and the 1533 already installed? Trying to work out what I need to do the installation. I appear to have the t91 remote, the controls unit that would mount under the dash and the antenna. I guess I also need a specific wiring harness, and one have any experience with this? Thanks in advance for any tips. Regards Jim
