i need a TPI harness and i will also need a maf, unless its a speed density harness 91-92 then i just need the harness

 

Ive got a 90-92 SD auto harness for $130

Emissions and AC were cut out, so I dropped the price

 

ok cool, im talking to a guy about which one i need for my specific setup SD or MAF as soon as i figure it out ill let ya know

 

Ill help you along

85's were their own deal, but 85 ECMs are the worst

86-89 were MAF, a few minor changes over the years but nothing major

90-92 were SD and identical for all years and makes

If this is going for your 91 RS, you've got two paths. V6 to V8 is plug and play with any 90-92 SD harness. TbI cars need a few pins changed at the C207 and the buffer box bypassed

 

well right now i have a 3.1 V6 and im swapping to a LG4 (carbed 305) but, im putting TPI heads and a TPI setup on the motor, and i plan on puttin a little bigger cam in it as well. and i plan on removing the smog pump and A/C. and i have a ECM for SD and MAF

 

This harness will work just fine for you. Let me know if you want it

 

yes i want it
