injector question

ok first off i have a 87 that im doing a na-tii swap and im just workin on finishing it up. well i noticed that the injectors i bought are from a 88 tii. can i still use these if i shave the offset nub of so they will fit into my wiring harness? or do i need to get injectors from a 86-87?

Trimming the inside of the injector plug with an exacto knife is the better way to go. The injectors will stay in place a little better than if you trimmed the tabs off. If your '87 had low impedance injectors originally, you'll need to remove the resistor pack to use the high impedance '88 injectors. Disconnect the pack, and jump all 5 pins on the harness-side plug together.

howdo you tell the differencebetween high imp and low imp? because these are the same part number as the ones used in a 86-87 tii,just the tab is offset rather than in the middle.

You just said it. The easiest way to tell is the tab.
