Great product, directions are not as good as they could beThe directions are not explicit in that you'll need to solder into the ignition coil wires, but they should be. Additionally it is better to get ground from the bolt that holds the cabin fuse box and power from an "add a circuit" slim fuse kit. Check out Cravenspeed's instructions for adding a vent gauge pod kit: https://www.cravenspeed.com/nd-mx-5-vent-gauge-pod-kit/ . That way you'll end up with less soldering on the ignition coil wires. The way I did it require only one ignition coil wire to have its insulation removed and soldered too.
You'll also want to get some high temp tape. Google for ignition coil tape. I found a good one for Audi/VW/BMW on amazon for $7.
There was no good instructions on how to route the wire through the firewall, which is the hardest part. I went in on the hole for the steel cable that is used to release the hood latch. It has a nice little rubber shroud to keep the passenger cabin clean, and I had to cut that a bit with a razor blade to get the tach wire through. DONT DRILL! It is unnecessary. To get to the hole requires careful manuvering around hard brake lines, so I had my wife's little hands help me out, but you could definitely do it with some long calipers or a pair of hose clamp pliers.
I routed the tach wire under the brake booster because it looked the best, but you'll have to be careful to keep the wire off of the intake manifold. Not sure it matters, but I used some of the provided zipties to do so.
I should mention the kit comes with all the mounting hardware you'd want for the actual shift light. I mounted mine on the steering column in front of the tach gauge. The wires hide nicely in the shrouds of the dash. I'll try to remember to take pictures and post them here sometime.
Note from FM: we recommend crimped connections instead of soldered. Also, high temp tape is not needed because you are not dealing with the high voltage wires, just the trigger wires.
Amazing shift lightThis thing is amazing. Wiring up is easy and setup is a breeze. Nice and bright with many adjustments.
