87-88 AEM EMS on a 90?

[alloyguitar]

So here's my issue. I have the opportunity to pick up an AEM EMS brand new in the box for a really good price from a buddy of mine who got out of the supra game, but it's for an 87-88 (yellow plugs)

...my car's a 90 (grey plugs), so the plugs are different.

Case and point I was considering just making a small adapter fields harness to adapt the one onto the other.

I don't recall what the differences are between the two, but if it's not motor-related, then I probably don't have it anymore. Lol.

no difference save for pin arrangement. Of course you could always repin

Cool. I couldn't remember if the physical plugs were different or not.

They are different.

Well, fuck.

Oh well, making an adapter harness isn't a huge deal. I was just wondering if anybody has done it. I don't forsee any problems, but you never know...

I have the "plugs" from an 87-88 ECU that I removed to do a standalone PnP harness. All you need is the same thing from a 90 ECU and connect the correct pins and voila...PlugNPlay!
