When I installed the PLX wideband a couple months ago I hijacked the A/C Pressure signal on my ECM for the wideband 1-5v output (this allows the Datamaster datalog to show the AFR). As a result I have not used my A/C since.

This week I got hold of a high quality switch and installed it under the center console lid - I can now switch the ECM signal between the A/C pressure sender and the wideband output.

Biggest pain was running the wires, but was a fairly simple job.

Hello A/C !
