I'm going to be retro fitting one ive just got (Cheers Guzzler), but have a few q's. I know they are not very accurate, but are good enough for what i need.

Is the loom already part of a 90spec car, or was it an add on? Also, is the fuel sender a different unit to the normal? If anyone has the multilug that connects to the back of the comp, id be v grateful for it
