looks like they are C4 calipers then. thanks guys.
i'm still doing the wiring. haven't had much free time last fortnight so not progressing as well as i'd hoped. i've attached a pic of a circuit that will keep my dash LEDs bright at day and dimmer at night. also, the other attached pic shows the back of the dash panel with the wiring for the 4 LEDs, 4 on/off switches and a 2 speed fan switch.
