Yep. On 90s with secondaries removed it is a good idea to hard-wire a shunt across the switch - the only way to "default" the switch in FULL, come what may! (Those that might not know, when the secondaries are deleted, the ECM is programmed so that the primary and secondary injectors each share 1/2 of the fueling duties. Should the POWER switch, for example, switch OFF or a contact open, the secondary injectors are cut off, and the fueling suddenly goes
way lean!)
