i just got my ls in my hf and used the ls harness and i have no spark and im told by hasport to use the stock hf harness im pretty confused now i have the pr4 ecu in there some one please help

 

yes use the stock hf harness...is it still obd-0?

 

yeah still obd0 what ecu do i use

 

You use the hf harness and a obd0 pr4 from a manual teg.

 

OBD0 PR4 from 90-91 Integra LS - you need to use the HF harness because of the wire loctions in the connectors - for instance, the HF has the igniter wire in the driver's side connector, where the Si and LS have the igniter wire in the passenger side connector - in the HF harness driver's side connector, only one wire is in the same location (in the connector) as the wires in the Si or LS connectors

 

k so put the hf harness back in run my pr4 anything else

 

k thanks i will try that i hope thats it thanks for the help

 

you should have one connector on the HF harness that you won't need - it was for the EGR valve

 

k well i will et u know how its works thank s

 

car fired up 1st try thanks everyone

 

ok so i have jacksons hf in my crx still obd0 and i need to know how to convert the ls harness to work with the hf motor. if someone has a diagram or a link to a diagram so i can repin this harness so i can drive this slow pos
