We cleaned up the wiring. We have an engine management harness
that is based on the Miata OEM harness. It is tied to a slightly
modified stock MGB/GT harness.
Since we relocated
several components, we had to re-route many of the engine management
wires. Some needed to be shortened, others lengthened. This was
pretty tedious, time consuming work.
carefully tested everything as we went along.
When finished, it looked like a factory installation.
We did similar things under the dash. The MGB/GT dash harness is
separate from the engine management harness (lower right). They
are tied together with the ignition circuit in the engine bay.
In a Miata, the computer is behind the passenger seat, so we put
it in the same spot on our MGB/GT.
