**how To Get Your 99-spec Gauges To Work**
lately ive been getting lots of Pm's on how to get the boost gauge to work so here it is.
its very simple just 2 wires missing that need to be connected. (- ground) and (map sensor signal)
(GROUND WIRE) - find a bolt thats grounded to the chassis and run a wire from there to the small bolt in the back of your 99-spec cluster that i marked [ADD GROUND HERE] in the picture below.
(MAP SENSOR SIGNAL WIRE) - find the map ->(pressure) sensor signal wire on the far right harness connector on the ECU the wire is green with a yellow stripe and has silver dots, next splice a new wire to it and run it to the back of the gauge cluster and connect it to the small bolt that is labeled MB or [ADD MAP SENSOR SIGNAL HERE] in the picture below.
post back your success!

i seem to have 2 problems with mine... I wired the boost gauge the way you have it shown and that seems to be working fine. The problem i have that the oil light is on in the instrument panel. I don't know if this has anything to do now that i don't have oil pressure gauge with that oil light so this one came on.
the other problem is that when i turn the ignition key on, the milage shows and it's working fine. When i turn the lights on the milage screen disapears. If i turn it off it comes back on...
What's the problem there.
Thanks a lot.

Check your oil level sending unit on the driver's side of the oil pan. The sensor wire is fragile and can easily break.

Hey guys,
I recently purchased a MAZDASPEED white face, 300km/h instrument cluster to suit series 6 & 7 FD RX7.
I personally own a series 8 and I purchased the item in full knowledge it was for the series 6/7 but being an extremely rare item it took me over 6 months of looking to find this one... and being able to have the oil gauge over the crappy stock boost gauge seemed like a good idea... I was hoping to fit this item to my car as i have seen older fd's with newer clusters fitted and i knew it was as simple as running a few wires to map sensor, etc. For boost gauge. I have plugged it in and all the lights and gauges work immediately but when I go to start the car it won't start...?
It is related to an earth but I'm not exactly sure where to start looking or what I need to do.
Any help. Info appreciated.
Cheers,
Ty

Damn, you should have contacted us, we could have gotten you the white MS cluster in less then 4 weeks. Not sure how to solve your problem, try re-setting the ecu (disconnect the battery and press the brake for 20 seconds)
