My Son brought home a new to us F450. Cliped to the fuse box beside the master cylinder. Red thing in the background. This mindblower chip ??? was stuck on top. My truck has 2 relays there and a cover.
What are these relays for.

 

It's another eBay "performance" scam. Rip it out and dispose of it. If you tear it open, I bet you'll find a single $0.05 resistor in it.

 

There are some differences between the years, but I believe all of the relays are the same parts. Take a look at the picture below and compare it to your blank spaces and go from there. Looks to be the trailer relays though.

 

No No I got the mindblower figgered out.
Question is what do the 2 relays in the red socket do??

I unplugged them in my truck and can't find what's not working.

 

Thanx Sous, That explains it. I'll start another thread with pics an perhaps a few more questions.

 

1. Trailer Brake Controller Interface inside cab for a Trailer Brake Controller.


2. Trailer Lighting. Including Brake, Parking. Trailer Brake Actuator Power for Trailer Brake interface.


Both are N.O. Bosh 5 Pin. They must be installed by the Owner. Ford puts them in the Glove Box with Trailer Wiring Instructions.

 

Thank you SMT for adding that info. We will have to get her ready to tow as soon as we get a few things sorted out.

 

OK Picachu, Since you mentioned it I thought I'd explore this MindBlower doo dad. I had already googled it, "bad", "tear it out", "hell it aint our product".

The garbage man won't come till Thursday so I dug this bad boy out of the can and cut it open. this is the mystery chip.


Not sure what it does but it only hooks to the ambient air temp sensor wires with these clipies. So the only thing it could be doing is lying to the computer about ambient air temp. Thinking this is still a good idea, I'll move that sensor to my YETI, Hell it makes ice

 

Well it looks like you got a worthless resister mod that they installed on the wrong sensor.

They were supposed to have clipped that to the ICP sensor wires. The trash is a good place for it.

 

I would take it if the case was still good, but alas it got torn up, of course I would rip the gut....errr the wires???...out and replace with an actual raspberry Pi (or arduino board) and actually program it to do functional things...LOL (course I am an IT guy and like to tinker with things like that for my own amusement)....oh well, glad to see another flea-bay resister "mod" get tossed in the bin where it should be! Knowing me I would make it a turbo timer, and a few other functional things that I would want...but again this is me and my computer knowledge and curiosity kicking in here I guess...

 

On a gas engine you can put a resistor on the AIT sensor and it'll add a drop more fuel. I guess technically it could do the same on a PSD, but I doubt it's enough to notice a difference. That people get $50 on fleabay for a resistor is ludicrous.

 

Lol. That's hilarious! And there's bound to be leagues of people saying what a great product it is so they don't have to admit they got ripped off.

 

Well at least they didn't lie... they said it'd blow your mind!

 

just like throttle body spacers!!!

 

I hope I did well when I bought blinker fluid.



It was only $75 on ebay.
