Thought I'd start a thread on my Volvo project, it's my first ever ECU installation and a steep learning curve but I'm enjoying it so far!
I've nearly finished the wiring in the car but I've got a really stupid question before I install any wires into the Speeduino connectors. I've got a UA4C (this one: https://diy-efi.co.uk/product/speeduino_ua4c_ecu) and the pictures show which pin is used for what. My question is which side of the connectors do I look at when following the pin numbers in the diagrams? Are they numbered as though I'm looking at the port in the ECU case or as though I'm looking at the connector with the loom coming out the other side?
