Yes - pin extraction - it's going to become a hobby of mine sometime in the coming months, so while I was out hunting down 18kOhm resistors for something else, I asked about pin extraction tools (for the pins and sockets in the connectors attached to the back of the fuse-relay board). Radio Shack only has the tool for .093" pins/sockets - ok for the connectors near the ignition coil, but too big for the fuse-relay board. The second place I went to had the 18kOhm resistors, but no extraction tool. The third place had everything you could want, including the smaller extraction tool, but wanted $50 for it. Well, I can either find it somewhere else, or go back and buy it there in a few years when I'm insane.
Anyway, I found something online - they sell a couple of tools for .062" pins at $8 and $14 and another for AMP connectors at $21.38, but the size isn't specified. Anyone happen to know if a .062" is right or close enough? -And if the AMP tool would be right? It (the $21.38 AMP) looks like the $50 tool I saw in the store today.

Yeah, you're barking up the right tree here - thanks for posting the links!

I have the MO-305183 tool myself, works for most pins, but not the big ones.

Hey, Action Electronics lives up to their name! The post office gave an impressive performance too... I order on a Thursday just before 4PM their time and shipping's complete Friday and it's in my mailbox on the following Monday. Less than 3 days from Calif to NJ - and with their cheapest $3.77 USPS shipping. I'm impressed.

Anyway I got both the $8 .062" pin extractor and the AMP extractor. The .062" tool turns out to be too small. The pins on the relay board are actually .062", but the ends of the female pins in the connectors are flared out, so the .062" tool doesn't fit over them. The AMP tool works perfectly though, so if anybody needs one, obviously get the AMP tool, but if you want to get extra pins also, get .062" female pins - the AMP pins are actually too big. I measured some female pins with my smallest drill bits - a 1/16" (.062") bit fits the pins in the connectors we have on our relay boards as well as .062" pins that I got from Action Electronics. My next larger bit, 5/64" (.078") fits the AMP female pins, so AMP pins are definitely too big. To make a long story short, get the AMP tool and .062" female pins.

Pin cleaning ideas -

For the female pins, put a drop of electrical contact cleaner on a 1/16" drill bit, insert, twist and give it some in-out action (by hand, not with the old Bosch 5 Amp elect drill).

To clean the males, attach and solder a .062" female pin to the end of about a 6" piece of hanger wire - maybe bend a bit of the end of the female pin in so it will have an abrasive scratching effect on the male

, bend a T into the other end of the wire, put a drop of cleaner on it and knocka youself out.

Smoothie,
do you know by any chance if it is possible to extract the pins from the
connectors on WUR/AAV? I found the partnumber for the connector but do you know the partnumber of the pins??

I was able to remove the pins from the connector for the window
wiper (flat pins), but not those from the headlight raising mechanism (round pins)without severely damaging both pins and connector.

I have bought a new connector for the headlight m. and new pins, but looking at those I still do not understand how these pins can be extracted.

Thanks in advance,
Duncan

Sorry, I've never needed to do anything with those [WUR/AAV] connectors. From just the look of the AAV and CSV connectors, and assuming the WUR connector's made the same way, my guess would be that they can't be disassembled.

Never had to play with the headlight connector either, but I'll take a look tomorrow and see which size tool fits. Should be either the Amp or the .093"-er.

As noted in my post in the other electrical thread (started by ideola) you need the round extraction tool for those pins - the AMP-Molex extraction tool on this page for Mate-N-Lock connectors, clearly shows the AMP part # of 305183 in the photo:

Yes the Amp pin tool #305183 works on the headlight motor connector - pops those suckas right outta there. I tried it on the wire connector only. If the motor side connectors' pins are removable, the same tool should work there too.

Scratch those previous thoughts on pin cleaning. I finally got my wipers working reliably and the correct tools are included in a set of small needle files. A flat file's good for cleaning burnt male pins and a round works on the females.
Apparently the pins are tinned copper or brass. Once burnt and cleaned, they're copper colored -

I'm trying to make a frankenstein main engine harness to repair some fire damage. I need to switch out some female pins on the DME connector. It seems that the tool you would need is different from pin tool #305183, because the hole is square. I checked the other thread that Ideola started, and I couldn't really find what I was looking for in the links that 924RACR posted there. Any thoughts?
I'll post some pictures in a few days if this doesn't seem clear.
Thanks!

Resurrecting this old thread....

Action Electronics does indeed live up to their name (very fast shipping!). I'll add my confirmation that the AMP pin extraction tool fits fuse box plug pins perfectly.

However, the 0.062" female replacement pins are about 1/4" too short! They fit nicely on the male side of the pins, but the length causes them to sit too far back in the plug - not giving as good of a connection.

In a pinch I think they'll work (I had to use one for lack of another choice), but keep an eye out for something longer. Once you press the plug into the fuse box, you can press the particular wire that has the .062" pin down onto the pin to connect better. But there is a chance of it working back up.

Anyway, just an FYI.
