Name that connector

[6sevensparks]

hey guys im new to hot airs. im trying to figure out what these connectors are from anyone please help me out ?

the one sitting on the top left of the ECM. i have a feeling it some kinda of diagnostic connector since some wires go to the ecm ... but i was also thinking it could be a fuse block connector

and these two have no clue what they could be for...

im doing a 85 GN swap in a 87 rx7.. so my whole wiring is gonna be custom

second pic ......... 2 wire connector is for boost gauge on digital dash not used when map sensor is present...... 3 wire connector looks to be power antenna from the relay on the right side of the glove box.

first pic looks to be c437 connector i basically connects the dash to the main engine harness. ecm to the fuse box and dash ,, check engine light ecm power dash ground map sensore to boost guage .... these are some off the top of my head it is a very important connection

one more note. all 5 of the bundled wires from the map sensor and the plug with 2 wires in the second pic go to the connector pictured in the first pic.

i never found a pinout for that connector i have the shop manual and traced the the circuits to that plug. from memory. 5 wires i described already. boost gauge or boost light ... ecm power.....ground from instrument cluster to main ground... 2 or 3 going to the communication link under the radio..... check engine light......
i am out of town and will be home this weekend and think i have it all written down i can post what i have then.
