i used those crimp on splices so there was no soldering and it made it pretty easy to get into tight spaces. the nice thing about them is when you remove them there is only little cuts on the wires, no cutting needed though.
wire guage size so as not to clip the wires? I may be jumping the gun because i'm just reviewing which one I want Apexi or Greddy... not sure.
The wires my guess are 16 gauge wires.
For anyone looking for a turtorial to install the Apexi Auto Timer in the Speed3, lemme know.. I did mine last night with the O2 Sensor wire and it works great.
I intend on taking pics and writing up a document sometime this weekend.
It might be that I am expecting something to happen, the skip is probably just me.
Did you check to make sure all of your connections were solid?
