i havent had a real good look.
anyway, just pulled the old cluster out and put the new one in, odometer works yay. fuel guage still works, temp guage still works. tacho doesnt, obviously. now the fuel low light and the brake light flash on occasions, as does the battery charge light (has done for a while), so there is obviously a poor wiring connection to them or something along those lines.
will research more about getting the tacho to work, but in all honesty it probably doesnt matter to much as once we eventually get another car for her this will more than likely go to the wreckers.
