72 all wired with tbi couple of questions
truck starts and runs great , but when going down the road and wanting to step hard on the gas truck bogs way down , but if u ease in to it easy it runs fine, here is my couple of questions, i used a wiring harness from 90 suburban,put it all on after wards i had to add 12 volts to the injectors, and to the fuel pump relay. and tie my fuel pump wire in to the relay .then it started right up.but i do not thing it is right, at end of harness for tbi goes in to the fuse box and right now that is not attached to nothing, not exactly sure on how to wire up that tbi,also i dont have the trouble shooting plug are the check engine light hooked up . does that go to end of harness some wear,can some one give me some info on hooking up this tbi harness,
