Attesa And Abs Issue

[Slattery Gts-t]

My car was off the road for 3 months with a blown head gasket and iv finally got it back together and going again but now my ABS and 4WD light on the dash is constantly on

Iv found that the 4WD relay under the bonnet isnt getting its +12v switch so i ran a wire from the battery to the power out pin where the relay plugs in and the abs unit seemed to spring to life and the ATTESA ecu finally started showing me some error codes (21,61,62). i Started the car and the abs light come on after a few seconds then a few seconds after that the 4wd light come on again.

So obviously im not getting any power to the ATTESA ecu or ABS unit all because im not getting this IGN +12v switch to the relay, Also the the +12v that feeds the relay is only getting 11.5v when the battery is showing 12.7v

While the car was sitting i accidently left an interior light on completely draining the battery so i replaced it with a blue top optima

Im out of ideas as iv tripple checked every fuse and cant find a dud ? a wiring diagram would be really handy
