^ Nice. I was definitely serious about a bulk purchase for other people, so keep that in mind as you go along.

Definitely! Once I get it buttoned up and tested on a couple of cars (MGargano and mrrock will probably be our official testers) I'll package it for retail sale. Perhaps MicroImage could be the exclusive distributor.

Yeah! What he said! Him first!

I was really starting to lose my patience with this yesterday thanks to my non-responsive system, but now I'm officially psyched again!

CTScott · 08-21-2009, 01:19 PM

Two down, two to go. The front right and rear right are now done...

MGargano · 08-21-2009, 01:30 PM

Wooo! Halfway there!

vten · 08-21-2009, 01:49 PM

great Jobs guy !! when the module is ready, let me know .... I'll take one for sure

CTScott · 08-21-2009, 11:13 PM

OK. After successfully emulating all four sensors, I moved from breadboard to a packaged prototype. For ease of handling the prototype, I mounted the switch to the module. For a production unit the switch input would be two more wires that could be connected to single pole switch (mounted to the dash, center console, etc.).

In the pictures below, you can see that the OC sensor connectors are not connected to the sensors. There are six wires connecting the bypass module to the OC ECU (four signal wires and two power wires). I tapped the harness at the sensor connectors, but one could actually make the connections, right at the OC ECU, eliminating the harness to the four sensors and making it far neater to install it under a race type seat.

And, on with a flick of the switch:

Dude your freaking great!!!

MGargano · 08-22-2009, 02:13 AM

Does any of this effect the passenger's seat belt light and/or chime? For example, if you arm the airbag, does the seat belt chime go off if its not buckled?

vten · 08-22-2009, 03:01 AM

I want it

Yes. It is just like a person sitting there, so if you arm it and the seat belt is not latched the seat belt light comes on. In the pics, I had the passenger seat belt clicked. You really wouldn't want to arm it unless you actually had a passenger, to avoid an unnecessary popping of an expensive airbag, which also results in the upper dash having to be replaced.

Ok gotcha.

The OC ECU is the module attached to the bottom of the seat and has two connectors. One goes to the SRS ECU and the other goes to the fours OC sensors (gray 12 wire connector). My module taps that gray connector using six of the 12 wires.

I received the Eggo Waffle box today (and it was lacking waffles). I did a quick test of your OC ECU and it is fine, which means that the issue is either with one of the sensors or a wire. I'll check it out tonight to find out for sure. Either way, it won't really matter, as I'll be shipping it back to you with one of my sensor bypass modules.

Do you want me to clip the harness off and tie it directly to the module, to keep things neat under your seat? (I'll ship back the rest of the harness with the sensor connectors).
