Electric Fan Conversion Question

[Tonyrodz]

Nit sure what Tony means by a different design. There’s a place on all the NBS fuse boxes where the fan relay/ fuse box slides on and clicks into place. There’s little protrusions on one and grooves in the other. If yours doesn’t have those you can screw or rivet it in place. I just went out and took this pic on my 02. It’s a clean, factory look. Mine slid in place. It’s the triangle under the fender mount. And you don’t need to worry about replacing fuses. They don’t blow. Aftermarket is another thing- those will. The top pops off for access. View attachment 449524

The fuse box on my 03 was different. Didn't have that extra "triangle " on it, that's why I bought an 05-06 style to go along with my fan conversion. Weird. Is that your original fuse box/cover Mark?

Yes, that’s what I meant. The harness should come with the add-on plastic housing part that holds the relays/fuses and that part just slides onto the 00-04 fuse box. It did on mine anyway as far as I remember. I believe it came with the harness anyway. It’s been awhile. @ScottyBoy should chime in here anytime.
Edit: I looked at his post where he is selling them and I do believe I bought the top cover that’s goes over both fuse boxes ( the regular one and the fan one) but the actual fuse/relay/junction block or whatever you want to call it just slides onto the regular fuse box housing.

Oh cool. Yeah that all makes since now. I'll have to snag that cover too.

Thanks!

Yeah, I sell just the harness and relay block. The whole plastic cover is something completely separate. But on my 2001, everything fits under my stock cover. The only drawback is there's no access cover to access the relays and fuses. If I need to access them, I have to unblock the fender brace and pop the entire cover off. Still pretty easy though, less than 4-5 minutes to get it opened up.

I went to the junkyard to look for fan parts. Spoke with one of the guys there who's a LS fanatic. Knows every hack to man and helped me with a lot of stuff in my build. I told him I was looking to do a electric fan swap and GMT900 brake upgrade (I'll put notes in separate post about that). He says the Cadillac NorthStar parts are AWESOME and recommended electric fans from that. They had a good set of NorthStar fans at the junkyard. He sold me them for $40 so couldn't really pass that up. The crux is they aren't direct fitment. They appear to be same width and about same height. He said he uses zip ties with clips on them to mount them. Then drills a hole for the Christmas tree mount on the radiator hose clamp. Seemed worth a try for a mere $40. Also they are 9 blade fans, unsure of motor wattage.

Did you grab the plugs for them?

Did you grab the plugs for them?

That's what I was just wondering as well.

 

[Matthew Jeschke]

The thought had crossed my mind but unfortunately, plugs were gone. Harness nearly completely picked apart already *sigh*
