Fitted a 'plug n play' option at the weekend - didn't fancy sticking wires in holes, especially the one shown in the photo :twisted: sorry Clemo :oops:
The connector shown above is pin 86 - at least it is on my car - and if you earth that you will blow fuse A10 which also feeds the ECM IIRC. Maybe a friendly photoshop wiz can put it right?
I hard wired two relays together and simply plugged them in [having removed pin #5 from the AC relay first :wink: ] along with a Carlton fog light switch. This was a pain as the teminal block in the dash was unclipped :evil: You can get to it by dropping the glove box, providing you have skinny wrists, like wot 'er indoors has :-D

BTW the relay bank shown is under the upper dash cover so no need to stand on your head - still a pain to get the fan relay out tho' :evil:

If you remove all the relay units from the board, and undo those two 10mm bolts, you can get to the underside of the fuse-box. No more standing on head in the footwell :lol:

Theres a 30A fuse supplying the load side of that relay. Just be careful that the relay is seated back properly. You dont want any dodgy connections causing a hot junction! Thats how some car fires are started.

and that could be why i have no power to the 2 fans :poke:
