Hi Kurt,
You will find all the information you need on the GoMoG site Plus 8 page
at http://www.gomog.com/plus8.html with links to other sources around
the internet as well.
The original 14 CU system was developed for the California emission regs
in the late 70's and early 80s and then used on TR8s and SD1s throughout
the States with a lambda sensors. It is a Lucas analogue ECU with the
trusty Bosch L-Jetronic airflow meter and injectors.
In 1983/84 it was installed as an expensive option in the UK Rovers with
the lambda sensor "looped" or closed off and the resistor values changed
from the earlier US system to increase power.
In 1989/90 LR/Rover went to a digital ECU with a Hitachi airflow meter
and different injectors ect. The systems are as unalike as chalk and
cheese.
My guess is that have mistaken the Lambda sensor circuit for the "cat
signaler".
Take a look at the wiring diagrams and other info. If you need more,
ask.
