Im just wonderig will the HKS TM's harness fit to the Apexi Pen's size turbo timer, because i have been checking the harness for the apexi TM but cant find one averlable for that.
And also i have been to my local performance shop they told me that they still dont have the HKS harness instock either,
And last is that the DIY TM install is easy?? will that cause big problem if i mess up the installation??

dude this is in the wrong forum...

To answer your question, to my knowledge the new apexi tt should be able to use the hks harness. I have the Blitz DTT-DC tt and I used the HKS harness. Hmmm the install is pretty basic, but if you mess up you'll for sure know. You won't be able to start you car.

it fits i have the same combo
