Can anyone point me specifically to where the octance loop connector is on an 89.
I have been looking by the passenger side wall by the LH and EZK relay and can't find it.
I did find two connectors that i'm not sure what there function is shown below. A Green and White Molex in the first photo, the other photo has an amp connector located below fuse panel.
Can anyone tell me there function?

There isn't an octane loop on the '89 - the knock sensors take care of the same function. The octane loop was only on the '85 and '86 models (at least in the USA).

Well that makes sense, any ideas on what the connectors are?

Upper photo is the connection from the EZ to the coil drivers (near the front bumper).

Lower photo is the where the CO-pot on ROW (non cat) plugs in.



What is that air temp sensor for in the upper photo? Must be '89-up, because it's not on my '88, AFAIK.

Porken It's aftermarket temp sensor. The car is an 89 that has digital dash factory outside temp sensor. When I replaced the rear view mirror with an Donley auto tinting it came with air temp sensor. Figured I would put it to use. Thank you all for the info.
