If you question yourself on DIY electronics applications in a high ingress and noisy EMC environment.

Ex.: Where to buy a metal sealed IP67 box and what type of connector should I have for my project.

Question no more, everything should be described here for your cheap solution. Just follow 5 easy steps.

Tools you need:

  • Torx screw driver
  • Cutting disk
  • Cutting knife
  • Multimeter
  • Hot Air Gun (optional)

Step 1: GO TO NEAREST CAR JUNKYARD

CAR JUNKYARD YES

It has EVERYTHING you need.

Just go there and ask for your components like I did: ECU box with cable connectors and some fuseboxes

TIP: Choose less corroded units, you won't be able to drive the bolts.

Step 2: TAKE ECU APART

Take your newly bought/got ECU apart to discover what you have inside.

Automotive PCB quality says for it's self a work of art.

Yes it is a pity for your next step, but there no much solution I found more, I am an artist of destruction.

Step 3: CUT THE PCB

Use your disk cutter for even separation of the connector and the PCB module

Step 4: INSPECT THE WORK

Inspect if you havent made any damage for your valuable connector

It can get quite expensive

Check any not intended short circuits, cut some unnecessary routs and the connector is ready for wire soldering for inside.

You should use hot air for desoldering for your new PCB application if any.

Step 5: PUT EVERYTHING TOGETHER

Now the room of IP67 box is ready for your freely programmable automotive application.

Put your project circuits inside the IP67 box, don't forget to use 2 side adhesive tape for boards and isolation.

Use all the IP67 benefits of the box :)

<p>How do you get ECU's so cheap. In the UK they are really expensive even from scrap yards. Because the car breakers know exactly how much new ones cost, they charge</p><p>about half the price of a new one.</p>
There is a pile of ECU and Fuseboxes. I said that I need nonfunctioning ones. The purpose is for hobby, the ECU will be cutaway only for connector and box. Also some cables. So anyway it is placed for metal recycling. He took 10 EUR from that amount on the table. He got more than from metal.
<p>This is great information! I love finding things at the junk yard! </p>
<p>Thanks, I am happy to share</p>
