Sorry for the thread jack but does anymore know what the 05 efan connectors are called? I have ls1 efans and would like to convert my harness for the 05 efans.

 

They're just called the harness side connectors for 05 efans...I have some somewhere, but I'm not sure where they are since I haven't unpacked everything since I moved. If I can find them before you get them, I'll shoot you a PM and maybe we can work something out

 

Let me know if you find them I'm definitively interested.

 

Sounds good, I'll go digging for them today, they're brand new

 

I got two pigtails in my toolbox, still in the packaging as well.

 

thanks, looks like someone beat me to it.

I was looking on a the auto parts website and it seems there are 3 different radiators depending on A/C, and tranny cooling or are they all the same?

 

Sale's still pending, ya never know...keep your eye on it just in case....

I'm aware of two different radiators, one with provisions for an oil cooler and one without, not sure about three. When I ordered mine from the radiatorbarn.com, I just put in the info for an 03 HD or something like that...guess you could use an 05 1500 silverado, or a silvy ss. I wonder what the differences are? I guess that the radiator is now available without trans cooler provisions since it is standard equipment from 05+, and 4.8's in those years were offered with a manual trans correct?

I'm going to guess that the three options would be with oil cooler, with trans cooler, and without trans cooler. I wonder what the ac has to do with the radiator? That shouldn't make a difference, but who knows.
