    Does anyone know what the proper name for the short power accessory (power seats, windows, and locks) wiring harness that plugs into the fuse box is or if anyone reproduces them? I'm not having any luck finding one.
    Cheers,

    Thanks for the help.
    Jim - I'll call lectric monday to see if they have any and how much they want for one.
    John - Thanks for the offer of a picture. I was able to find a picture of one already.

    I called both Lectric Limited and American Autowire earlier today and neither offers a repro splitter. I know there are at least a couple different styles - I have seen both 2 wire and 3 wire splitters. Some time ago I called Painless and they (at that time) did not offer one either.

    As far as I have gotten so far is that I have located a source of the original GM-style connectors for interior GM wiring and ordered several male and female connectors in case I had to build one. The place I found is called Del City (www.delcity.net) - I have no affiliation with this business, but we will see how it works out.

    I have a 3 way splitter sitting in front of me. It's off a 70-72 Skylark harness, I don't know what year. It's a heavy orange wire w/ black stripe deal, but it doesn't look like it plugs in the fuse box. It looks like it went though the fire wall, 'cuz it's got a small grommet on it. I don't know it's worth, I'll post a pic tomorrow.

    Here's what I have. You could easily put a plug on it for the fuse box. I know these are HTF, because I remember looking for one for my GTO's years ago. I don't really need it, but I'm not giving it away. SAM_0066.jpg SAM_0067.jpg

    Buicks look like this one.

    Frank, this is the power lead which apparently runs through the firewall .... it appears the same or similar to the power lead wire reproduction sold by American Autowire and possibly Lectric Limited.

    There are several variations I have seen on Buicks and other A-bodies. I think the difference may be the power option load on the car. I have seen just a 2 way splitter (a plug-in to the fuse box power 'tang' ... see pic below) with two pigtails with female connectors and then the 3 way (and even 4 way) for the cars with more than two power options (see pic in prior post and pics below).

    These pics were pulled from George Nenadovich's Buick Performance Club How To section (great resource):

    Edited by adding pics:
    Here is the 4-way splitter .... probably the rarest of them all. The power lead (black arrow) plugs into the fuse box on one end and then on the other is a 3 way connector which has 3 female ports to plug the power accessory wire connector into (3 white arrows). The 4th port of the 4 way splitter is actually on the special "piggy back" connector that plugs into the fuse box (single white arrow) .... you can see that there is an extra female port for the 4th power accessory wire (probably for power windows, power locks, power convertible top and ... power trunk???).

    A 3 way splitter would not have the special "piggy back" connector, but would have the special 3 port female connector on he other end. A 2 way splitter (the ones I have seen) is just 2 pigtails coming out of the male plug that goes into the fuse box. ***keep in mind that these power accessories utilize a relay which energizes on demand .... this is not the entire wiring schematic involved with powering these options.

    I think Frank's type is for the 64-67 style cars:Do No:

    I too had no luck with calling the harness manufacturing companies, but I believe John's picture (post #8) is the type I am looking for. One is bound to turn up somewhere. I just have to keep on the lookout for one. If I find a source for a repro harness I will be sure to let everyone know.

    I do have to say that George has been very helpful with some odd pieces so it can all go together for a factory-like install.

    Cheers

    I'll check some other harnesses I have, Robert. Thanks guys for help ID'ing. It's definitely a 70-72 'lark harness splitter. Could be like Ken said, depended what the option load was. It does look like it passes through the firewall, but it would be simple to clip the wire and put a terminal and red plug on it. Years ago I would see them on ebay and they would bring 25.-35.00 on there.

    Ok, so check this out. I mentioned earlier that after searching several wiring vendors, I found Del City on line and then found that this vendor carried a stock of GM style "Packard Type 56 series" electrical connectors. At about .30 to .35 cents a piece, I thought I give them a try because I can certainly build a short "harness" if I had to with the correct wire color coding, all I needed was the proper connectors to plug into a stock GM electrical system.

    The order was waiting for me when I got home tonight. Here's what I ordered (the shipping was more than the parts):

    So, I can at least build the short splitter harness if I need since it is not as simple anymore as going down to the junkyard on Sat. morning to find one. I will still be on the look out for one, but be able to move forward on my project. I will start looking for other fuse panel type electrical connectors when I go to the junkyards because I can rebuild these connectors with the new metal terminals from this vendor as needed and build small leads or harnesses (I can still find some late 70's and 80's GM cars). I will also be looking at the big Del City catalog they sent me .... if you order from them, make sure to check the box for the free 400 page catalog:

    Any thoughts or suggestions, please let me know.

    Up until a few years ago, you could walk into any NAPA and buy the terminals AND plastic connectors. I stocked up a long time ago. Then if I went to the boneyard and saw weird connectors, like the red fusebox ones, I would pop them off, toss them in a ziploc and the yard wouldn't charge me. Yeah...some are getting hard to find now.

    Check out Motor City Restoration Parts & Supplies on the web. This outfit has some affiliation with Inline Tube, Inc. and might be a division for other types of resto parts than metal lines and tubing.

    Anyway, search for part # INL10611 (or INL 10611) which is described as a '70-'72 Olds Cutlass/442 "power trunk lead wire jumper". Note: This one for the Olds appears to plug-in to the power wire to the glove box light and scavenges power from that power wire.

    The wiring/connector assembly looks to be essentially identical to the 2-way splitter discussed and pictured earlier in the thread which Buick used, except that I think the actual wire gauge is different (thinner wire).

    I will be replacing this thinner wire with a lower gauge of wire (thicker) for duty for Power Windows and Power Seats - but I believe that this is the only difference between this assembly as purchased and the 2-way splitter used by Buick for multiple power options.

    And, if you need a 3-way splitter configuration, see in one of the pics how two of these can be connected to give THREE power leads from one plug-in source (fuse panel 'PWR' port) by plugging two of these connectors together (you still may need to upgrade the wire for higher amps for PWs and PSeats). I hope this helps.
