Golf mk1 1800t agu original wiring and ecu

Good morning all, I currently have a mk1 golf with an agu engine in, it does run with a qpeng ecu system, I have researched and found it possible to put the car on the standard ecu and loom, does anyone know who would be able to wire the harness and ecu, I have reasonable mechanical skills but feel that the actual wiring may be beyond me , thanks in advance

Try VAGTronic. He did my loom on my '79 with an AUQ engine. Easy to pulg in. Only 4 wires from memory. They can also add in to the loom to run the rev counter.
