just what he needs, a few pics...you should be able to do it on your own...on diesel manor they even tell you what wires to splice for power of the gauges for the lights and pyro box..good luck and take your time tapping the manifold...
go to www.dieselmanor.com and they have an install section that show pics of diferant locations to put things...that should give you an idea of where to put stuff...lots of factors and options on what you can do...i did my pyrometer on the manifold or you can do it post turbo but it will not be as accurate...this web site should help you out, or call them im sure they would like to help you...nice people hopes this gives you a start
