Use the A/C if you don't have it.

In your fuze box there is a fuze for A/C if you don't have A/C hook it up to that fuze. Here is a diagram on how I did mine.

jeff31753 cant email so read post

hello well i got the electric fan hooked up...i used it as a pusher in front of the rad, i dont have a airconditioner so no cooloing coil in front of rad. that gave me tons of room to install a electric fan in front of the rad. anyway i hooked it up to a power source that i found in the engine compartment that tested hot with a test light with the ignition key to the ON position..and no power to this wire with the ing, key at OFF this way i wont forget to shut it off one day. ( this wire was not attached to anything just hanging there i dont know what it went to have never had it attached to anything ) ..i got my fan at autozone 60$ it comes with all you need to put the fan in...once i got it in i ran the car at idle and it got to about 180-190 degs. with in 5 minutes at idle which it did not with the stock fan...( i remove the stock fan and clutch ) now i have not taken the car out for a drive but i dont like the fact that it got up there in temp so fast at idle..and the electric fan does not blow the same amount of air at the engine as the stock did..but it's alot quieter than the stock fan..in fact if you really want to hear all thats going on in your engine just remove the stock fan and listen...now i hooked it on front of the rad. incase i need to install the stock fan back on the car in the summertime here in florida...i think if your stock fan is doing it's job, keeping the car cool...you might want to think about just keeping it...perhaps two smaller fans a pusher and the other a puller will do a much better job..some people have that set up...i went with just one electric..to see how that goes...anyway good luck and check out the archives there is a few post on the elctric fan...type in electric fans in search and it will come up...michele

That happened on my old 240.

There was a short in the combination switch for the running lights. Why it didn't blow the fuze I don't know but it got hot enough to melt the fuze box and put a hole in the plastic cover. I fixed the short, replaced the fuze box and it never did it again.
