Somewhere there is a diagram for the pinouts off a 1990 car, can't find em, can someone point me in the direction please?

Also looking at http://diyautotune.com/diypnp/apps/n76/usdm-mazda-miata-9495-18bp-mt.html I need pull ups on VR2 to 5v & OPTO to 12v, is this the same on a 1.6 aswell?

Cheers

PS so nearly have my DIYPNP ready to laod on the firmwares, good evening work

okay, confused now, here is the 90-93 pin out



Admittedly I haven't pulled the old ecu from the car yet but that pinout looks nothing like the one I have on my DIYPNP connector

That looks like the same connector i've got for a 96 1.8.

I'd wip out your ecu and try plugging the connectors into your connector board. See which one's fit. Looks most likely to be the two outer one's

Makes sense now, the "2" section on the first diagram match the "4" section on my output board, willhave a looksee at my ecu in the morning (that'll explain why the pictures of DIYPNP connectors I have found on the web have numbers written on them)

Bloodyhell, it works (on the bench at least!)

Off to rip my ECU out, see what happens next.....
