Need help with VDO
i know i know. but for the life of me i can not find anything specfic about the installation of the VDO temp guage into a 94 d90. closes thing i find is a reference to having to tie it into a vdo temp sending unit and thats it. and no direct instructions in the faqs, tech articles or the custom mods. what i would like to know is it just a plug and play with the vdo guage (part #310105) or do i have to buy something else so that it will work properly?
