I'm still figuring out what the previous owner had going on with this fan wiring so I can get it back to factory once and for all. Before I start messing with fixing the wiring on this secondary fan relay, I just need somebody to double check me if you would, please.

This is on my 1990 L98 Coupe.



Does it look like Black/Red on the secondary fan relay has been cut here? Also, there's a Dark Blue/White wire coming from the ECM and into to the Secondary relay on whereas the diagram says it's supposed to be a Light Blue/White wire connected coming into the relay from a Dark Blue/White wire coming from the ECM.




Does it look like fusible link E has been cut and removed here?



Thanks for input.

Or maybe the red wire is just cut after the connection to fusible link E. That makes more sense to me.

I dunno, maybe. I haven't traced that red wire yet to see where it goes. It was more of an aside kind of deal while I was thinking of the relay wiring. I have a feeling it goes into the secondary relay, too.

I'll figure it all out eventually, I guess.
