Pre-89 into a 91 help

[bis_1315m]

can anyone tell me how I can switch the plugs on the pre89 harness to my 91 plugs I know there are tsrm's for this but Im not that good at reading electrical diagrams or would it just be better to get an 89+ harness im in a hurry so I need to know as quickly as possible thanks

oh yeah if I buy a 89+ harness will it still fit the ecu that the pre89 harness came with the connectors are yellow

do you have lol

you dont have too.. and there is a benefit of running a pre89 ecu as they have a revlimiter north of 6500 (6700 i think) were as the 89+ (at least my 91) had a revlimiter of 6400..

you can start by looking at the 1jz wiring on the body pins and figure out how to pin it..

You will need either the 89+ harness connectors or pre 89 body connectors..
