I was looking at similar bits online as your photos... Not sure how to buy the size I'd need. I HATE online shopping for that reason. Other concerns, and I'm NO electrician,,, is that the clip would drive up resistance inline and then, that that type of clip would contact neighboring coil spinz and shorten the current travel thus lowering resistance...? As you know, it's very tight. But again,,, i am NO electrician.
lol
Even insulated connectors would work --so long as you peel the insulation off first. Clean the resistor wire ends off by scraping with a sharp knife, exacto blade or tie like. Yow want a really clean surface on the wire before you join the ends. Just keep the resistor from touching anything else, shorten the splice with a dremel if nesessary to get it in there.

Good morning folks.
I went in and removed the fan and stuff to get to the resistor pack. My problem was that one of the 4 wires in the resistor was burnt making it so speeds 0, 1 and 2 supplied no power (I think) to the fan. Only 3 and 4... Also, the fan appliance was gummed up and it took a LOT of amps (never measured exact) to turn it. I freed up the fan axle with some marvel mystery oil and replaced,,, at the same time made some adjustments wrapping the burnt wire over itself for contact (wouldn't take solder,,, something to do with the resistor wire NOT liking solder)... Anyways, on reconnect,,, fan flowed nicely on 0 and now worked on 1 and 2. Great!
Silly me - I didn't like the wrapped wire "fix" that I had come up with. It felt COMPLETELY temporary... So,,, brain I am,,, I took a spare resistor pack (got VERY lucky) from an 85 and put it in line,,, buttoned everything up. NOW,,,, MBS!!! Like crazy!
I read here about the removal and capping of one of the resistor pack leads. Lead 8!?!?! What have people heard?
QUESTION --- does (has) the removal and capping of lead 8 on the connector work without causing damage? Have any scary reports come back since this solution? I worry about frying another pack IF it doesn't have this safety function. What happens when it overheats??? I ran some little tests when I had everything apart,,, and on some of the dash settings the resistor wire get RED HOT quickly without the fan and yes,,, the fan does good work to regulate some serious heat in the tunnel...
I don't have a 12yo with a skinny arm and I'm lazy! Does capping lead 8, work? OR,,, do i needto take this whole thing apart again?
What say you?
