Thanks for your response Peter , there's no hurry mate . Just need to know in the simplest of terms how to set it up properly .
The diag's they enclosed were a bit confusing for me & I don't want to stuff anything up just for the want of patience.
Will wait till I hear back from you.
By the way I've managed to lose my parking lights at the front. The neutrals are fine but not getting any supply to the active side. The rears are OK & of course the fuse link is OK. Got me stuffed ,
By the way I meant to mention that I replaced the 260Z Alternator with a 280ZX in that Tacho set up blog don't know if you did the same , also it is compatible with the S30 V/regulator.
