eliminate resistor

The fan should blow towards the engine (pull air thru rad.). The 3 wire connector looks wired correctly. Ground (cut off), low speed (to the 'long' end of the ceramic resistor), high speed (to the end of the resistor closer to the fan motor (no resistance)). Resistor is in there to provide 2-speed fan operation. Some folks (alot) just jumper across the ceramic so the the fan always runs on high (when it's on)... you will need the fan relays and the associated 86/87 wiring to connect to the harness in order for the 86-87 ecm you are swapping to control the fan..

Thanks for the info! So if I want the fan to run on high speed only all the time, I can eliminate that ugly resistor right? Just want to make sure it wont have any harmfull effects on the fans itself.

Thanks! Bill

Hey Brad
Do you have a direct link to Caspers? I just searched the web and came up with casper the friggin ghost! lol!

Are there different kits? Is there one you recommend? I am doing the 87 ecm swap, MAF, TT chip, scanmaster and all that so I should be set to go with the kit you mentioned.

Thanks! Bill
