ECU pin? What are they called?
1 Attachment(s)
So I received an S4 harness that needs to have a few connector at the ECU terminal to be replaced.
What type of terminals are these? As in "what do I type into amazon to buy new ones?" Noob question. I know. Sue me. :lol: |
|
those don't appear to be the correct ones since they are tinned, the ECU connectors are gold plated.
|
No one has ever re-pinned their harness? The other spade terminals are already in the basket. Just really need to know what these are lol
|
More then likely there is a brand/manufacturer and part number on the header connector for the ECU. That would narrow down the type of pin or socket you would have to order.
|
they are made by amp/tyco, and i'm sure styx's reference is close but i would do an alternate search for gold plated terminals. the ECU side is gold plated, just to keep everything equal and prevent possible dissimilar metal conductivity or corrosion issues.

I was just wondering the same thing as I'm sure other people have. With these cars being 30 years old some of them have been through a lot and could use some rewiring. I think there's 2 connectors with the gold going to the ecu and the silver/tin going to the front harness. I'll check out TE 170352 or 170353 and post pics to compare if I can get a hold of some.
From over at the 1986-1992 supra forums I found "pin part #'s for above yellow ECU connectors: 170352-1 (tin plated, 22-20 awg, strip) 170352-2 (gold plated, 22-20 awg, strip) 170353-1 (tin plated, 20-16 awg, strip)" http://www.supraforums.com/forum/sho...-terminals-etc.) It wouldn't surprise me in the least if both Toyota and Mazda used the same manufacturer as car companies often do. Ordered 100 of 170353 from mouser electronics, they're silver in color and probably tin plated instead of gold but sell in lower quantities and like Devin said I couldn't find the gold plated anywhere. Anyone know what the larger silver pins that go to the front harness are? Will post side by side when the smaller pins arrive. https://cimg9.ibsrv.net/gimg/www.rx7...da9dd21822.jpg bottom https://cimg0.ibsrv.net/gimg/www.rx7...cbbbb2ebfc.jpg side https://cimg1.ibsrv.net/gimg/www.rx7...eb48745dd9.jpg top |
Can confirm they are the same pins as the Supra (thats where I learned the part numbers). Not terribly surprising given that the RX-7 ECU is made by Denso

if the gold is unavailable then you might just try the tinned ones, or see if you can get them gold plated. probably wouldn't be extremely expensive by a local jeweler, can't be more than a couple grains worth of gold required for all of them.

So here's the pictures of the ones I ordered as promised. Silver are new ones and gold are stock OEM ones. Pretty clear to see they're a match. I'll fit test them later when I get to that point in my project and update this is for any reason things go wrong with these but I'm not worried about it.

For anyone dying to have gold contacts, masterelectronics.com / onlinecomponents.com (same company) both have stock; just be prepared to pay more in piece price and shipping than the tin plated offering still available from Mouser.
