Spade terminal block jumpers Vs. multi crimp

This guy does some absolutely amazing wiring panels: http://www.yellowbullet.com/forum/showthread.php?t=232215

Looking at this stuff, I don't see any jumpers on the terminal blocks. The few pictures of underneath that he has make it appear like he is sometimes putting two wires onto one metripack pin.

As I look at the diagrams I'm building for my SC300, I only see a few places where co-pinning might make sense for me, but I see a lot of places where using spade jumpers for terminal blocks would make sense (headlight wiring coming off the panel going to right and left, for example): http://order.waytekwire.com/products2/M50/300/200/500/1/Jumper%20Strip%20For%20Term.%20Block/Double%20Row%20Terminal%20Blocks/Terminal%20Block%20Junction%20Block/

Is using jumpers on terminal blocks bad? Multiple spaded wires onto one terminal? I can't think of any easy and electrically solid way to distribute voltage from one wire to multiple wires. Splices/soldering totally sucks.

What are your opinions and experiences?

It's fine. The secret to reliable wiring is to keep it from vibrating. Keep it motionless (and of course dry) and it'll last for decades. Like aluminum, copper work-hardens due to vibration. Over millions of vibration cycles, the copper gets harder and harder, eventually cracking through.

Running two wires into one connector pin is fine only if it's sized to accommodate both. I've seen cases where someone's clipped off half the strands on both wires in order to make them fit. Ugh...

Oh man, I wish I'd known about those relay/power distribution blocks when I started the MG wiring. I'm half tempted to rip out a bunch of wiring now...

When I rewired the MGBG2.3T I used a combination of spade terminals and terminal blocks, Weatherpack connectors and PosiLock connectors. One neat thing was using multiple 8 fuse panels to run specific systems like lights and computer components.

The ONLY good thing about that car actually.

I've got a couple of nice fuse panels, but the ones with the integrated relays? Wow, that would clean things up. Make the work a whole lot faster too.

Here you go, Keith, Bussmann power distrubution blocks

I started looking for them as soon as I saw those pictures. If the MG wiring gives me any hassles at all, one's going in. You can get them at Waytek Wire, but the official PDF is much clearer as to what the various parts are - thanks for that.

Yeah Waytek sells the ISO 280 relays (mini and micro) as well as the Bussman panels. The panels use Metri-Pack 280-series terminal pins, so I guess I am going to buy a 280 kit and a nice crimper. I've planned out most of my wiring so far, and I'll put the diagrams up eventually.

I was just recently searching for something on google, and came across this post that had a link to my control panels. So yes, those are all of my control panels and they have changed alot in the past 6 months if you check out that link again. I do have a website, but its not completed yet. It is www.racewiresolutions.com, and will be active within the next month.

If you have any questions, feel free to email me at smknta95@hotmail.com

whatever happened to that car?

OEM makers use multi-spade connectors afixed to a terminal. I see no reason to fear doing this.

Similar jumpers on terminal blocks. There are various pre-formed ones for various terminal blocks, just for the purposes you mention. Again, I see no reason to fear them.

Wow. I was just going to post a thread about this a few days ago, before adding some gauges and warning lights to the Miata. It takes me forever to design this stuff in my head. I'll definitely check out this site.

To run all my ancillaries inside the MX6 (gauges, wideband, boost controller, turbo timer), i used a terminal block from RatShack with jumpers down the side. I set up two of them. One for power, one for ground. Power is fused in-line before the block.

I have 12 power points, and 12 ground points that i can access in a matter of seconds. Makes installs easy, and very easy to troubleshoot.

I was planning on doing a more elaborate setup with the Celica when i rebuild it. It can be a lot of work on the front end, but awesome to deal with on the back end.

Happened to be in a marine store this morning looking for some boat parts and found a variety of buss bars made by a company named Sea-Dog found at: http://www.sea-dog.com/categories/electrical-panels-connectors-battery-accessories/buss-bar I will be wiring a car soon and really want to establish a really good ground system as I been told that is probably the major problem when thing don't work as they should. Just thought I would pass it along!

Those bussman blocks are hot.
