So, I was working on re-looming my injector harness to clean it up a bit, and it occured to me that I might not have the right harness. I don't seem to have any wires connected to my knock sensor!
I'm running a Super 60 main harness. The charge air temp wiring comes out of the main harness at the firewall, just behind the intake manifold. Then, coming off the passenger strut tower, there are two plugs. The main plug for the injector harness, and another small oval plug with a single wire going into it, though the plug has the capacity for two wires.
The single wire going into the plug is black with a red tracer. When I bust out the '88 L body wiring diagram, the black with red tracer is intake air temp. But, I thought that the plug coming out from the firewall was intake air temp, so I peel back the tape and sure enough, that plug has two wires, one of which is black with red as expected for the charge air temp. So I'm pretty sure that is correct.
So, now the plug with the single wire that plugs into my unknown origin fuel injector harness, I would expect that single wire to be for the knock sensor. But, the color is wrong. From the '88 diagrams, I'm expecting black with blue (or was it green... either way) Does anyone else have a Super 60 harness that they can check?
So my injector sub harness has the two pin plug on it. One pin goes to a connector for a charge air sensor. This corresponds to the wire coming from my super 60 main harness. But that doesn't make sense. Who would need two charge air tem sensors??? The other wire in that plug goes to the knock sensor. But with the orientation of the plug, there is no wire coming from the Super 60 harness to connect to the knock sensor.
So, what I'm trying to verify is that I should remove the Charge air temp wiring from the injector sub harness and move the knock sensor wire to the other spot in the two pin oval plug so it's connected to the single black with red tracer wire coming from my super 60 sub harness.
Does that make sense? I don't know what all was added to the Super 60 harness from the '88 L body harness, so I don't know if the knock sensor wire was an addition and simple added with whatever color they wanted to use... and if they somehow put it in the wrong pin in the connector... I didn't get any documentation with my Super 60 harness, so if anyone has the info sheet they could post, maybe that would answer some questions too...
