Ok got my fuel pressure and wideband A/F gauges in today. Along with a group of wires to set up the triple gauges. Can I splice the stock boost gauge wires to this new set up and then use the original harness for the constant 12v, switched and negative. Would this work?

 

I tapped my stock boost gauge and ran a constant to my fuse box. There is no constant on the stock gauge.

 

Not sure why I was thinking constant. The pink would be switched, so you ran your own constant from the battery to the fuse box? And did you put an inline fuse or just use a extra slot from the fusebox? Hate living in Italy, their are no autozones or car part stores. Everyone takes it to the shop. Being from the states, its natural to do all you own work...

 

I just ran the wire into an extra slot, didn't buy an inline fuse but it's probably a better idea lol

 

3am here, nothing is open in Italy on Sundays either. You'd laugh at all the gauges just hanging from the dash and stuck til at least after work on Monday guess I'm just gonna have to roll with it haha....
