Service loop for rpm and timing light hookup

Since the TSX doesn't have sparkplug wires. Some of you may wonder where to hook up for timing light or rpm for the dyno.

Service loop
Here is the service loop (grey color) right behind the valve cover. It's attached to the wire harness with two zip ties and a piece of blue tape. You have to remove the blue tape and zip ties in order to connect the inductive pickup.


Inductive hookup


RPM at idle
The tach in the dash is amazingly accurate. It matches to the instrument perfectly. I noticed how accurate it was on the dyno. Now it's verified. Idle spec = 750 +/- 50 (MT)

Can you change the base/mechanical timing on this 2.4 engine?

Thats the only reason I could think of why youd want to hook up a timing gun.

The TSX doesn't have a distributor to adjust base timing. However, you can still hook up a timing light to verify timing for troubleshooting, or use the inductive pickup point during a dyno session without removing the sparkplug cover.
