i pulled a bad 90 b16 out of my crx and sold it a few months back. i just dropped a b16A3 in today, but the head was stamped 98. im using my old manifold but i was just wondering if any sensors on the block or head changed locations over the years. i have 2 plugs that dont seem to have a home

 

no they are the same. the original dist plugs would be different, and there'll likely be a crank flux sensor on the oil pump but the rest is the same.

 

i have one rectangular plug left, its a 4 wire connector with the following wires. red w black stripe, yellow w black stripe, green with white stripe, and white. anyone know what this is for?

 

the dist was wired up for use with a gsr dizzy. this plug might have been unplugged the entire time i had the car i just dont like seeing loose wires hanging around the bay.

the plug is the same as the one in this diagram and it says "useless sensor"
think i found my answer there....my harness was hacked up by the previous owner so i am always suspicious of it i guess lol.
