COP Trigger Setup
Re: COP Trigger Setup
Make yourself a sub harness that has your distributor plug on one end and the cam/crank sensor connectors on the other end. Pin the cam and crank sensors to the CYP and CKP sensor locations, respectively.
You'll still need to run four wires from the ecu to the coils for signal. You can use the TDC wires and the original ICM wire for three but come up short by one, so might as well just run the four wires separately.
For the tach signal, easy button when deleting the distro is to run a wire across the dash inside the cabin and tap into the original ICM pin the ecu. Obviously this will not be active on the Link if you have it set up for COP, but you can easily configure it as a tach output in the software.
Your coil pack subharness is easy, you have 12V coil power at the second distro plug and you can use a ring terminal to ground to one of the distro mounting lugs. Then you just need your 4 coil signal wires. Done and done.

Re: COP Trigger Setup
Looks like you purchased the linkecu hc92x. On that ecu, you would need a tach booster for that plug in board. Id also recommend the k24 cam sensors, due to ths plug orientation pointong downward. For the connectors and pins, i ordered racespeconline. Theres pinouts obviously in the help file or in the hc92x manual. You would then have make sure you have the specific cam sensor wiring. K20 and k24 have different wiring positions. I got that information from haltech i believe. Unpinned the distributors pins, pinned in the cam sensor pins into correct location.
Im pretry sure i still have my notes from when i made the harness and did all the wiring. if you need help with anything just pm me. Or start a thread

Yes I have the HC92x Link ECU. I've figured out that people have been depinning the plug at the dizzy or making a sub harness. I figured someone would offer one, but that isn't the case. Would you happen to have the part numbers for the K24 Cam sensors? I have seen somewhere that the actual length of the sensors are different depending on which ones are used so I know that is something to possibly beware of.

Wiring is not my thing at all. I would figure someone would offer a subharness, but clearly I'm mistaken. I may jump out there and make a sub harness, but I'd much rather leave it to a professional. Now that I have the wiring outputs from the thread on the Link forums, I feel more confident as far as knowing what needs to go where exactly.

Re: COP Trigger Setup
The B-Pro is not actually "released" just yet... a pre-production unit has been exposed at SEMA 2025 last week. It isn't even listed on their official website yet. This system should be ready for public consumption in early 2026.
