Nitrous and TPS sensor location

[Cash1333]

So I am installing a nitrous kit on my car and I have a WOT switch, however, with my progressive controller I can run it with the tps sensor instead. So I am trying to determine where a good pick-up connection for the tps to pick up the correct throttle percentage.

Here are the pin-outs for the 2015+ metal throttle bodies vs. the plastic 2008-2013 throttle bodies:

Disregard the arrows - those were for anyone that wanted to make an adapter harness to switch from the older plastic throttle bodies to the newer metal ones.

Do you happen to know if anyone has made these harness pigtails available to swap from plastics to later metal housings?

No one that I know of offers these, but I've also not asked.

So do I tap into TP signal 1 or 2?

[Steve M]

I don't think it matters - there are two signals for redundancy/error checking, but they should have the same output.

Check with Nth Moto. They made me some a few years back to make that swap.

you can order them from this site, not cheap but easy

Appreciate the link for sure.

Seems excessive on the price; I'll play match-up later. No chance anyone already knows the connector reference numbers too? LOL

Typically, these signals would be opposite of each other. One would go 0-5v, while the other would go 5-0v.

[TBSH]

Need to figure out which is rising and which is falling.
most all controllers will do either for TPS WOT switch.

Interesting...did not know that.

Their connector reference numbers are their own, which makes it hard to match up to what's needed.

Regardless, all the info they need is in this thread: https://driveviper.com/forums/threads/26494-Metal-Gen-5-Throttle-Bodies-on-a-Gen-4

Specifically, this part:


Dan,

Thanks for the excellent tech tip! I'd bet dollars to donuts that the terminals Ballenger is using are Tin. It took some digging, but I think I found terminals that use the correct materials.

If you are assembling these yourself, you'll still need the following parts:

2 x https://www.bmotorsports.com/shop/product_info.php/products_id/4587 (those will plug in to the existing plug on the vehicle's wiring harness)
2 x https://www.bmotorsports.com/shop/product_info.php/products_id/4503 (those will plug in to the new throttle bodies)

Those will come with crimp on terminals, which are likely to be made out of tin (they don't specify on their website). Toss them, and order the correct ones (Silver/Gold plating) below. You'll also need some 20 AWG automotive TXL wire. Plenty of sources online for that.

There's pretty much one source I could find for the connectors and terminals: https://www.te.com/usa-en/home.html If I had to guess, the OEMs get their stuff from them. I'm not in the automotive industry, so I don't know for sure.

The plugs for the plastic throttle bodies are based on what appears to be an older design - the TE Connectivity MQS series of connectors. The metal throttle bodies use a newer TE Connectivity MCON connector, part number 1-1718646-1.

For the connector that plugs in to the old throttle body connector (MQS), you'll need at least 12 of these (gold - silver doesn't appear to be available): https://www.te.com/usa-en/product-5-963716-2.html
For the connector that plugs in to the new throttle bodies (MCON), you'll need at least 12 of these (silver): https://www.te.com/usa-en/product-7-1452656-3.html
You can also opt for gold with the MCON connectors: https://www.te.com/usa-en/product-1670146-2.html, but they are a little harder to source without ordering a ridiculous quantity (lowest I could find was an order of 100)

The MQS stuff is getting harder to source, but the MCON stuff seems to be reasonably well stocked.

I'll be ordering the correct terminals shortly, and redoing the connections on my adapter harnesses as soon as I can get the parts in. They are working fine for short term, but this isn't something you want to fail - ever. The right stuff is a little more of a PITA to find (took me about 2 hours of digging), but again, I've done the homework for you.

Yes, this isn't exactly an easy DIY project, but don't let that scare you away.

The only part that I'm showing is hard to source are the gold/silver MQS connectors (TE connectivity 5-963716-2 (gold), 5-963716-3 (silver)) - seems like you have to buy in quantities of 10,000 for those particular terminals.

Yep 0-5V always makes more sense when setting up the controller but the other is falling voltage.

Need to figure out which is rising and which is falling.

What is wrong with putting a voltmeter on both circuits. You can use a micro insulation piercing probe, they will not hurt the conductor.
