I have the 52mm Greddy electronic boost gauge - I'm having some problems with the wiring for it - the only things I have tapped in are the 12v source and the ground (from the ashtray), however there are 2 other wires (ignition and parking light?) which I do not know how to wire.

The gauge does not work with just the 12v and the ground connected. Help!

Go to www.mkiv.com ->tech -> gauge instal you will find all wires info.

Before final instal do the test with lights on and changing power of lights of OEM gauges. When I had mounting mine it was strange that when I made full light of OEM gauges Greedy was almost blac and vice versa. You have to make tests. Now I can only set the power of oem gauges light, Greedy is always max lighted.

Sorry fo my English:D
