N20 JB4 install notes!

For those in Canada installing JB4 for their N20 powered X1 here's a few notes.

1. The DME box seems different in that Burger shows their box as being empty except a few wires and fuses. The Canadian version has two boxes in it.

2. Routing for the JB4 trunk cable is difficult. I couldn't find an empty gromit or an easy one. I ended up using the one where the power comes through (3 larger red wires. I stuffed the trunk cable between the gromit and the DME box at the bottom.

3. #2 means that the DME box won't fully close.

Other than the issues with routing the cable out of the DME box, the install went smoothly and the set up seems to work well. Easy to change between maps even while driving.

I have a dyno appointment at Vex Performance on the 28th, I'll throw the numbers up here when I get a chance.
