turbo timer harness install?

[slowma70]

Hi, i will be installing a HKS turbo timer type 1 into my supra.. I want to buy the hks turbo timer harness but it says it only fit turbo models, would it matter if my supra came with an 7m-ge originally? or do they have different ignition connectors?



89 Supra N/a 5spd

Oo Thanks, that was quick.. Also where would i connect the wire that requires the rpm signal?

The tach wire on the Ecu pinout.
