Relay Work Part 2

I re-worked the relay board a bit while I'm awaiting for a few more parts to arrive.  Hopefully the poly fuses and PET covering will show up this week. Once I have everything laid out I'll start soldering.  

I ordered samples of male and female solder cup DB-37 connectors but I think that I may switch to the Molex 20 pin ATX connector.  I found a piece with a little over 12" of 18ga wire in my electronics junk box.  I think that this looks better than the db-37 and would handle more power too.  

Just off to the right in the pic you can see my free sample project box that I'm going to use for my wide-band O2.  When I'm done with the relay board project I'll post up re-work pics of my wide-band O2 project.  

Warm weather is just around the corner and I can't wait to get started up in the garage again.

Megasquirt DIY Relay Board Challange

I figured that I'd do something productive today since its still too cold outside to work on the notch.  I was going to just run a wiring harness to the engine and the sensors and wire everything up with a couple of relays and an auxiliary fuse  block.   

Most of the forums that I've lurked on recommend to go with the Megasquirt relay board to make the wiring job easier.  This isn't a must have just something that makes the job easier.   

One of the issues that I had with the relay board was the price so I've challenged my to see if I could DIY one on the cheap.  So far I'm into this project at zero cost.  The way that I've been able to accomplish this is by requesting free samples of some of the components.  Items like the relays were from my junk box.

I'm awaiting for a few more items to show up and hopefully I'll start soldering it up soon.

More Parts

Drivers side foot well to replace the rusty one on the notch.  I should be able to massage this one in no problem.

I didn't have any intentions of doing this but the price was too good to pass up.  Megasquirt-II here I come.
