You'll need to research wire harness ground location for your 1991 740 with Bendix Rex ignition / Regina injection.

Wire harness info can help.

Find the Mitchell Service diagram for 1991 740. See PDF page 23.

Have you checked for fault codes?

Also, the fuse and relay box behind the ashtray is a serviceable item as described on this page by forum member John Sargent.

Check for melted plastic around high current relays and fuses. DeoxIT-D helps greatly.

At 30 years of age, your 1991 740 will require more frequent or vigilant care as my 1991 240 does.

The relay location info in 740 on Dave Barton's site may help.

Merely relays:
