Question about my supra.

[suprflyusmc1]

I have a 1989 N/A Mk3. I'm wondering, like on the turbo where there was a difference in plug colors, yellow and grey. Is there a difference in plug colors for the N/A supra, and if there is how do I determine which plug color i have with out having a harness, or an ecu to look at?

the pre 89 are muilt color. the post 89 are all grey. no diff between turbo and n/a on the color. your 89 should be all grey. i think i got that right.


my old 89 had square motor mounts, but grey plugs and now is on my 87.
