I think Im going to go with Barkers for the Harness. He price seems really good, and he will do up a little switch plate with all the switches and lights you need, and then you only have to connect a few wire, battery positive, ground.. Pretty easy.
I am going to use the stock Gauges, mostly for the tach but also for pulling codes and such if there are problems.
On the air filter, I was thinking of using a Kinser filter. What do you guys think. Probably need to run his qualifying filer though, its made for very dusty conditions. Not as trick as Peter D, but I think it will flow better, and its cheaper.
Speed Partz, Kinser Air Filter - dwarf car, modified lite
I also found a trick filter setup from Rosson, thats pretty darn nice.
