Relays make the blinking happen, when they are receiving power on a ground leg it can happen. I suspect you have a few power and ground wires crossed, very common. Especially check the ECU power and backup power wires, and the main ignition wires (the big ones up by the battery).
You should be using the manual trans lower engine harness - either SR or KA they are almost identical.
